For tita = 120 degrees R = square root of Asquare + Bsquare - AB

[latheefshaik]

If A = B then R = square root of 2Asquare (1+cos tita ) / replace A with B

[badrinath]

I'm a doctor by profession
I show ur videos to my child
He improved a lot. ❤️❤️

[d.saijeeth]

If tita = 120° then R=√( A²+B²-AB) = √(2A²-A²) = √( A²) = A(or) B

[rameshnallapu]

Your classes are very useful for me sir. Thank you very much Sir

[rishikeshgs]

Sir answer for 28:49 question is R=root of a*2+b*2-ab and if you put a=b then u get R=a and R=b

[rafath.jannathhussain]

It was so amazing to learn sir with ur teqnique

[madhavipavan]

Cos 120 is equal to –1/2 SO A^2+B^2–AB

[dannyvallabhapurapu]

U r one of the few masters of physics sir

[kalyanmutcherla]

Sir excellent trick
I love your explanation

[praneethamadepalli]

Finally I found my physics teacher 😊♥️

[Rasayanika]

Sir second question, if the two vectors are equal vectors then a = b that means resultant are equal to under root 2 A square into 1 + cos theta

[narasimharao]

Sir super explanation nanu follow avuthuna and ma friends kuda chaputhuna

[bhaskarvijay]

Sir for 120 degrees I got R= root A square + B square - A B sir

Becz cos 120 = -1/2 na sir

[sandhyaarrojula]

Sir.
Parallelogram law of vectors lo..
Triangle law laaga rendintini join chesedhi resultant anukovach kadhaa

[venkatnaidu-gzln]

Sir I am class 8 i didn't understand this chapter when studying in my book but when I started listening to your videos I learned a lot.

[abhiff]

Sir I am getting answer of angle between to vectors is 120 degree is root A²+B²-AB

[Igoy_]

28:36
If theta =120⁰,
R=root over A²+B²-AB sir

Excellent teaching sir ...go ahead.

[saikadari]

Sir i small doubt two vectors parallel ga unte how resultant draw
