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

A

Increased and then decreases

B

Decreases then becomes constant

C

Increases and then becomes constant

D

Continuously increases.

Solution

up to when block have contact with sphere its net

$a_{ne t}=\sqrt{a_{t}^{2}+a_{c}^{2}}$ increases as $v \uparrow$ after that

only acceleration of block will be acceleration due to gravity.
