What is the angle b/w (p+q) and (p* q) . A) 0 .B) PIE/2. C) PIE/4. D)PIE
1 Answer
Shuvendu
Pi/2 because: a+b is on the plane on which a&b lie but a*b is perpendicular to that plane.so a*b is perpendicular to a+b

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.
