1) Assume that you have two objects one with a mass of 10 kg and the other with a mass of 15 kg each with a charge of +3.0x10^-6 C and separated by a distance of 2 m. What is the electric force that these objects exert on one another?
2) Determine what happens to the electric force in the following:
a) The distance between the objects doubles.
b) the charge on two identical objects doubles.
c) the charge on two identical objects doubles and the distance between the object doubles?
please help me!!!!
