If we assume vectors as X, then the magnitude of the resultant vector is also X. This is mentioned in the question itself.

To find the resultant vector, we have an equation: R² = A²+B²+2ABcosθ

Applying the above formula gives: X² = X²+X²+2XXcosθ

X² = 2X²+2X²cosθ

-X²= 2X²cosθ

-1/2 = cosθ

Therefore, θ = cos^-1(-1/2) = 120^o

ANSWER: ANGLE BETWEEN 2 VECTORS IS 120 DEGREE

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.
