Let R be the resultant . R=root of A^2+B^2 +2ABcosx

20=A^2+B^2. When at angle 60,R=root of A^2+B^2+2ABcos60. 28=A^2+B^2+2AB/2

28=20+AB. AB=8

A^2+64/A^2=20

After calculations A=2,B=4

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.
