Question

A particle of mass m is initially situated at point Pinside a
hemispherical surface of radius r as shown in the figure
A horizontal acceleration of magnitude a0 is suddenly
produced on the particle in the horizontal direction of
gravitational acceleration is neglected, then time taken by the particle to touch the sphere gain is
​

Answer 1

Answer:

C)√(4rcos(alpha)/a0)

Explanation:

Vertical component of acceleration× displacement/ acceleration^2
