A lead shot of 1 mm diameter falls through a long colummn of glycerine. The variation of the velocity v with distance covered (s) is represented by

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
In the beginning, due to gravity pull, the lead shot will be ac celerated and hence will move with increasing velocity for some time. When the viscous force balance the gravity pull, then the shot will move with constant velocity by shot. Thus option (a) is correct.
