6. calculate the force of gravity between a llama (m = 125 kg) and a gazelle (100 kg) when they are
20 meters apart. (2.08 x 10°n)

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.
