A metal sphere of radius ' R ' and density ' 
' is dropped in a liquid of density ' 
' moves with terminal velocity ' V '. Another metal sphere of same radius and density ' 
' is dropped in the same liquid, its terminal velocity will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
When the metal sphere of radius R and density 
is dropped in liquid of density 
then the
terminal velocity becomes, 
where, 
viscosity of the liquid.
Again, when another metal sphere of same radius R but density 
is dropped in same liquid, then the terminal velocity becomes,
