Dear pallavi
This is a problem of dimention
let
V = k λadbgc
where k ,a,b,c are constant
Now write the dimension of all the quantities
[ M0 L1 T-1] = [L1]a[ M1 L-3]b [L1 T-2]c
[ M0 L1 T-1] = [ Mb L-3b+a+c T-2c]
compair
b=0
-2c=-1 or c=1/2
and -3b +a+c =1
a =1/2
so V =k(λg)1/2

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
