Question

Q.21 Define charge. What do you understand by positive and negative charge ? Write down the expression for force between two charges.​

Answer 1

Answer:

A sphere of mass m and radius R rolls without sliding on a horizontal surface. It collides with a light spring of stiffness K with a kinetic energy E. If the surface (AB) under the spring is smooth and E = 7J and K = 10 N/m, find the maximum compression of the spring.A sphere of mass m and radius R rolls without sliding on a horizontal surface.
