JEE Main 2022 — Circular Motion Question with Solution
From: JEE Main 2022 (Online) 26th June Morning Shift
Question
A ball is released from rest from point P of a smooth semi-spherical vessel as shown in figure. The ratio of the centripetal force and normal reaction on the ball at point Q is A while angular position of point Q is with respect to point P. Which of the following graphs represent the correct relation between A and when ball goes from Q to R?
This question includes a diagram. The text above accompanies the figure.

Step-by-step explanation
At Q ;
The equation of motion of the ball isFrom figure,
From law of conservation of energy,
So, Eq. (i) becomes,
Ratio, constant
, which is independent of .
