Question

A sphere of 40 kg is attracted by another sphere of 15 kg with a force of 0.1 mg weight .find the value of the universal constant of gravitation if the center of sphere is 20 cm apart

Answer 1

Answer:

Two spheres of masses 1 kg and 3 kg are on a horizontal smooth surface. Sphere of mass 3 kg is given velocity

V = m/s towards other sphere such that it makes an angle of 30° with line of impact. Then, find maximum possible

loss of kinetic energy in Joule of two sphere during collision.
