JEE Advanced Physics 2015 Paper 1 #15 (#3) Magnetic Field

To donate:

Solve: A conductor carrying constant current I is kept in the x-y plane in a uniform magnetic field B. If F is the magnitude of the total magnetic force acting on the conductor, find the correct statement(s).

Sir I am preparing for the exam and there are very few people who provide jee advanced level concepts. THANK YOU FROM THE BOTTOM OF MY HEART 👍👍👍

When sir uploads a video, the first thing I do is to like the video and then watch it.

[pkumar]

Sir, next year I'm appearing JEE-advance. Any advice would be great.(please suggest a reference book). Love your video and analysis.

320g nitrogen gas is heated from T1 to T1+100K.The gas volume becomes V1 to V1+5L.
The gas pressure becomes 80kPa to 100kPa.
How to find T1, V1, Sir?

[tahycoon.]

a personal question sir,
why do you write everything in Caps?
i like your font!
keep up the good job sir thank you for every moment you have spent helping us!

I still have some confusion unsolved. Since you are using the graph of y=2t as an example to find its area under the line which is pretty obvious and easy to understand but what if I give you a graph of y=x^3 at the first place and ask you to find its area under a curve from x=0 to 2. I know the answer is 4 by using the formula of integration but what is the point of taking the anti-derivates to get (x^4)/4 takeing area under 4 order
the graph of (x^4)/4 the graph of it is different from the( x^3)
graph fourth of equation graph looks like shape of "W" and third order equation looks like shape of "N", what is the point of taking area the under curve of third order equation while using integral to obtain 4 order sir (only gives the orginal function back too existances)
i have comments in calaulus 2 ch1

Sir, I recommend you to try MEXT undergraduate exam. Which is quite challenging as well !

[kuljotbakshi]

but what if L and R have different numerical constants attached with them, then you obviously cannot write f proportional to (L+R) ( for instance the magnetic force comes out to be IB(L k cap + R/2 k think to remove this ambiguity a dl vector must be taken for separate orientations and the the formula (dl cross product B ) must be used which would unfortunately lead to a very long your take on this?
