A small metal ball of mass 
is dropped in a liquid contained in a vessel, attains a terminal velocity v. If a metal ball of same material but of mass 
is dropped in same liquid, then the terminal velocity will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
and 
be radii of the ball of mass m and 8m respectively. Then
and 
or 
or 
Terminal velocity, 
Since 
and 
are same for both balls
Thus, 
or
