A small ball is rolled with speed `u` from piont A along a smooth circular track as shown in figure. If `x=3R`, then

`What is the minimum value of x for which the ball can reach the point of projection after reaching C?

A

(a) `2R`

B

(b) `5R`

C

(c) `3R`

D

(d) `5/2R`

Text Solution

Verified by Experts

The correct Answer is:
A
Minimum velocity at `C: v_C=sqrt(gR)`
Range, `v_Csqrt((2xx2R)/(g))=2R`
This is the minimum value of x.
