like_who is waching this formula marathon for 8, 9 april jee😁😁

[hustlerjee]

Amongst controversies going on, on all other platforms, Eduniti shines independently.
#edunitianforever

[valleriebell]

It’s my last attempt Tommorow wish me luck ! Pray for me !!

[siddharthundefined]

Crazy to see how far we've come. From Units and measurements to the last formula marathon. Thanku mohit sir, for everything!

[subhranilkajli]

Legends watching this 1 day before jee mains

😊😊Who is watching this formula marathon before April attempt 😊😊

[usujjwalsingh]

Things that I have to remember for future reference from this video:
1. ε is permittivity and μ is permeability.
2. electric field at center of arc of a ring
3. use Gauss law to find electric field for symmetrical objects.
4. electric field due to a charged disc
5. self energy is electrostatic potential energy for a continuous body.
6. dipole formulae.
7. symmetry based q in electric flux
8. if two spheres are connected they will share charge until their potential become same, if the spheres and identical in shape and size then charge will becoem equal
9. capacitance formula of various bodies.
10. work done by battery (or a potential) = charge flown * potential
11. force between plates = q * EF due to the other plate (trick to rem)
12. connecting capacitors, if same polarity, less heat loss, so v1-v2 in formula, if diff polarity, more heat loss, so v1+v2 in formula
13. dielectric in ext EF or capacitor formulas
14. in 1 time constant, 63% is charged or 63% is discharged
15. CE formulas, don't be scared, see trick:
velocity = acc * t -> vd = acc * tau, acc = force/mass = qE/m so vd = qE/m * tau
i =neAv (yaad hi karna padega)
mobility is drift velocity per electric field
remember formula for rho

16. in conductor, T inc R inc so i decrease so vd decrease.
17. learn colour coding
18. use nodal method to find potential of different junctions and this is very useful for various qs.
19. cube resistor formulas
20. for max power is ext circuit then net ext resistance must be equal to int resistance of battery.
21. finite wire be careful of theta
22. don't forget number of turns in various formulas
23. closed current carying loop has 0 force in uniform mag field
24. in non uniform field B(x) the force is F=MdB/dx
25. M direction from S to N, magnetic moment =M =m d
26. replace:
k by μ/4pi
q by m
P by M

27. terminologies like angle of dip, apparent angle of dip and angle of declination. Angle of declination is the angle between the magnetic and geographic meridians.
28. oscillation of compass needle.
29. Curie's law (need to prac qs from this topic)
30. motional emf -> velocity must be perpendicular to length and B. polarity by v x B, thumb (right hand) points in + direction
31. mutual inductance: phi 2 = M i1 and phi 1 =M i2 ->emf induced is d phi / dt --> also M is same for a pair of inductor.
32. for two or more sinusoidal currents, find their resultant by superposition and then divide by sqrt2
33. by default assume values to be rms.
34. w1 and w2 correspond to Pmax/2 value. w2-21=bandwidth
35. vector form of reflected ray.
36. if mirror is rotated by theta, then reflected ray is rotated by 2theta in same sense. if incident ray is rotated by theta then reflected ray is rotated by theta in opposite sense .
37. for mirror m=-v/u and for lens m=v/u
38. spherical surface refraction, be careful about the sign of R, use proper convention..
39.

Mera exam 27th ka pehla shift hai. JEE mains B. Tech. ke pehle paper ko dene jaa raha hu. NO IDEA WHAT TO EXPECT. But after this revision before my final mock test, something tells me it will go well.
Two years have been leading to this. Absolute rollercoaster ride, y'all. I never could score more than 60 overall in class 11, maintained that tradition till 5-6 months ago, and then, I discovered this god. Over the past few months, i've gotten up to 140-160 after some pretty hard work. yesterday I scored 73, (probably stress issue after studying for nearly 13 hours with only 40 minutes for lunch and all that). But, today, on my this last mock test, I am going to finish these last two years strong, and come out of the exam centre happy tomorrow, knowing that, if nothing, I tried my best.
If I make it to IIT, Mohit sir ko party dunga!
Jo aayega sab like karo :)

























































































edit: boht zyada logo ne like kardiya, kangaal karke chhodoge kya?

From 100k to 230k in just nine months and that's when quality revision meets speed run. After my Exam, I would love to meet Mohit sir once at least. Thanks, Eduniti♥♥

[shreyapallav]

He even mentioned deleted topics timeline in description box so that JEE 2024 students don't waste their time! 🥹 You're a gem ❤ Watching your videos even being a NEET student coz you give detailed explanation no one can give. Thank you so much sir 🙏
