Condition for not sliding
f max>(m1+m2)g sin theta
0.3 m2 g cos theta>= 30 sin theta
6>=30 tan theta
1/5 >= tan theta
for p,q
f=(m1+m2)g sin theta
for r and s
f=fmax=mew m2 g sin theta

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.
