B and C accelerate downward at (2*3 -3)g/9 =g/3, let the tension in string connecting B and C be T.
3*g-T=3*(g/3)
solve for T
That gives the tension in the string connecting Block B and C.

first we take a+b+c as a system
(6g-3g)/9=a
a=g/3
now
force on C
3g-T=3*g/3
T=2g
accln=g/3 =>3g-T=3g/3 T=2g
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.
