A small steel ball of radius 
is allowed to fall under gravity through a column of a viscous liquid of coefficient of viscosity 
. After some time the velocity of the ball attains a constant value known as terminal velocity 
. The terminal velocity depends on (i) the mass of the ball 
, (ii) 
, (iii) 
and (iv) acceleration due to gravity 
. Which of the following relations is dimensionally correct
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
By substituting dimension of each quantity in R.H.S. of option
we get 
= 
.
This option gives the dimension of velocity.
