Question
A lead shot of 1mm diameter falls through a long column of glycerine. The variation of its velocity v with distance covered is represented by:
Options
A.
B.
C.
D.
Solution
When a body falls through a viscous liquid is velocty increace due to gravity but its velocity increases due to gravity but after some time its velocity becomes uniform be comes of viscous force becoming equal to the gravitational force. Viscous which increaes as velocity increases so curve (a) represents the correct alternative.
