6. The two blocks, m = 10kg and m = 50 kg are free to move as shown. The coefficient of static friction between the blocks Is 0.5 and there is no friction between M and the ground. A minimum horizontal force F is applied to hold m against M that is equal to – ( plz explain the solution in detail)
Let F be exerted on m. let there be no slipping,acceleration of two blocks at rest with respect to each other=F/(M+m)
force exerted by m on M=MF/(M+m)=normal force.,downward force of gravity on m=mg,maximum friction=(1/2)(MF/(M+m))
thus MF/(2(M+m))≥mg, F≥2mg(1+(m/M))
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.
