A 90kg person stands 0.5m from a 60kg person sitting on a bench nearby. What is the magnitude of the gravitational force that the 90kg person exerts on the 60kg person?
The answer is 1.44*10^-6N. I need to know which formula to use.

The formula for gravitational force is just G(m_1)(m_2)/r^2, where G is the gravitational constant, m_1 and m_2 are the masses, and r is the distance between them. The value of G is 6.67 x 10^-11 N-m^2/kg^2, the masses are 60 kg and 90 kg as given, and r is 0.5 m.

difference between fee and truthfully is that magnitudes have not have been given any course as a result the gravitational stress from earth is in direction of the sunlight and on the sunlight is in direction of the earth. do no longer understand what else to declare.
