Not surprisingly, Mr. Sul loves to slide around in his socks when the classroom floor has been freshly waxed. Mr. Sul has a weight of 800N and the coefficient of kinetic friction between his socks and the floor is 0.30 . How strong is the Friction Force that opposes his sliding?

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.
