3. Calculate the electric force that exists between two objects that are 5.0 x 10-2 m apart and carry charges of 2.5 x 10-6C and -3.2 x 10-C. Is this force attractive or repulsive?

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

The mass of a bowling ball is 10 kg and the mass of a ping pong ball is 0.015 kg. if the two objects are 5 meters apart, what is the gravitational force ?

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
