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

A

SHM

B

periodic but not SHM

C

not periodic

D

SHM for half a period and non-periodic for rest half of the period

Text Solution

Verified by Experts

The correct Answer is:
B

(b) After attaining terminal velocity, ball will move with constant velocity . Therefore, the motion of the ball is periodic but not SHM.

Two balls of same size but different masses m_(1) and m_(2)(m_(2)gtm_(1)) are attached to the two ends of a thin light thread and dropped from a certain height. It is known that the ciscous drag of air depends on the size and velocities of the balls. other than the gravitational pull from the earth and the viscous drag, the buoyant force from air also act on the balls, the buoyant force on a ball equals to the wweight of air displaced by the ball. After sufficiently long time from the instant the balls were dropped both of them acquire uniform velocity known as terminal velocity. When the balls have acquired terminal velocity, the tension in the thread is
