364158 Assertion :
If a man with a wrist watch on his hand falls from the top of a tower, its watch gives correct time during the free fall.
Reason :
The working of the wrist watch depends on spring action and it has nothing to do with gravity.

364159 A small ball is dropped from a certain height on the surface or a non - viscous liquid of density less than the density of ball. The motion of the ball is

364160 Assertion :
If the earth suddenly contracts, the duration of day will decrease.
Reason :
The angular velocity of the earth's rotation will decrease.

364161 An air chamber of volume \(V\) has a neck of crosssectional area \('a'\) into which a light ball of mass ' \(m\) ' just fits and can move up and down without friction. The diameter of the ball is equal to that of the neck of the chamber. The ball is pressed down a little and released. If the bulk modulus of air is \(B\), the time-period of the oscillation of the ball is \(2\pi\,\,{m^x}{V^y}{B^z}{a^q}\). The value of \(\frac{{xy}}{q}\) is
