AITS SELECT-6 😍ROTATION CHALLENGE JEE ADVANCED BALL ROLLING ON TWO SURFACES

HERE'S THE LINK FOR "AITS SELECT" SOLUTIONS SERIES ANNOUNCEMENT

(a) It is impossible to roll without slipping on two mutually perpendicular surface
(b) There will be only one point on sphere which has zero velocity
(c) There will be only two point on sphere which has zero velocity
(d) There will be infinite points on sphere which has zero velocity.

Did you people try out the AITS SELECT problem given at the end of the above video? Comment your answers 👇. Solution coming shortly 😊

[vardaandua]

Feeling confident, solved problem on my own from your channel .... i love your efforts and hardwork

[agrimmittal]

erm I think there is a question in puzzling problem, I think problem 52 it also had similar concept, the ball was not touching the ground, rather to points on the wall or something...

[prathamrana]

Thank u sir for clearing my doubt . I had doubt in past but no one can cleared my doubt as I am not in any institution. Thanks a lot sir 💕

[praneethng]

sir, I thoroughly enjoyed your videos
sir if possible can you make few videos in explaining some of the main concepts (only theory)

[vyomvarshney]

nice sir
nitin sir solved it as a clkass eg

[srikanth]

Sir question 1 is asked about points on the sphere but axis runs through the body of sphere then how can every point on axis can be on the sphere
Sir my answer is there are two points with zero velocity that are point A and (exact opposite to A)
Please explain

[VenuGopal-zpww]

Sir, how can you say that when two points are rest on a rolling body, the line joining those two points will be the IAR? We cant define their velocity directions, so we can't draw perpendiculars to velocity and see the point of intersection.

# 42 For my revision ( easy but conceptual(❁´◡`❁)👍)

[ponnapu]

sir plz answer this when you free sir is the equation torque=I alpha valid about any inertial point in space sir provided the system is rigid

[kanukie_]

Wow I thought ans would be 2 forget about iar

[simplephysics]

Please 🙏 others are requested to like diamond 💎 which is available in the form of videos here... please

[yashagrawal]

Sir in it velocity of com would be w.R/rt(2) if w is angular velocity ?

[swayam]

Sir can you please share the aits paper?
