Description

P#07
Compute the gravitational attraction between two college students of masses 80kg and 50 kg respectively 2m apart from each other. Is this force worth worrying about?

P#08
Determine the gravitational attraction between proton and electron in an atom of hydrogen, assuming that the electron describes a circular orbit of
radius .53x10^-10

P#09
A woman with a mass of 45 kg is standing on a scale in an elevator. The elevator accelerates upward with a constant acceleration of 1.2 m/s^2. What is the woman's weight as measured by her in the elevator
