2. Calculate the force of gravity between a new born baby of mass 4 kg and the obstetrician of mass 75kg, who is 0.3 m from the baby.
3. Calculate the force of gravity on a l kg mass at the earths surface. The mass of earth is 6 x 10 to the 24 power and its radius is 6.4 x 10 to the 9th power.
This solution provides equations and calculates force of gravity.
