=μMg=.08×(50×10)=40N
As T=200N>f
k
, thus a will also be towards left.
Ma=T−f

50a=200−40⟹a=3.2m/s

⟹α=8rad/s

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.
