  1. A man and his friend have masses 70kg and 60kg respectively. If they are seated 1.0m apart, calculate the gravitational force of attraction between them. (G = 6.70 × 10-11Nm2kg)
  2. What is the gravitational potential due to molecule of mass m at a distance r from it?
  3. Two objects of masses 80kg and 50kg are separated by a distance of 0.2m. If the gravitational constant is 6.6 × 10-11Nm2kg, calculate the gravitational attraction between them.
  4. The magnitude of a gravitational force between two particles 0.010m apart is 10N. If the distance between them is increased to 0.02m, calculate the magnitude of the force.
  5. What is the escape velocity of a body on the surface of the earth of radius R if the gravitational constant is G and the mass of the earth is M? (Neglect energy losses to the surroundings)
