To rotate it we need torque
Torque= force x perpendicular distance
If the length of string is short, it means perpendicular distance is short. So less torque is required
So is it difficult to move a stone tied with a longer string than a stone tied with a shorter string as longer string cause larger perpendicular distance

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.
