An object is at the top of a smooth sphere which is kept fixed. As object slides down after
\( \mathrm{P} \) being given a negligible side push, magnitude

W of acceleration of object during its motion till it reaches ground.
(1) Increases and then decreases
(2) Decreases then becomes constant
(3) Increases and then becomes constant
(4) Continuously increases.
