Two pellets, each with a charge of 1.5 microcoulomb (1.5×10−6 C ), are located 2.8 cm (2.8×10−2 m ) apart.
Part A
Find the electric force between them.Part B
What would be the mass of an object that would experience this same force in Earth's gravitational field? Please help I have a test and I have no idea how to do this.

1. F = k Q1 Q2/d^2
where k = 9 * 10^9
Q1 = Q2 = 1.6*10^-6
d = .028 meters

= m g = 9.81 m
