An object is at the top of a smooth sphere which is kept fixed. As object slides down after being given a negligible side push, magnitude of acceleration of object during its motion till it reaches ground.

Options

A. Increases and then decreaes
B. Decreases then becomes constant
C. Increases and then becomes constant
D. Continously increases.

Answer

C

Explanation

Up to when block have contact with sphere its net `a_("net")=sqrt(a_(t)^(2)+a_(c)^(2))` increases `v uparrow` after that acceleration of block will be only acceleration due to gravity.
