a +5mC at rest is 10 cm away from a+100mC stationary charge. (i) calculate the electric potential energy between the two charges. (ii) what is the electric potential energy when the +50 mC is 52cm away from the other charge? (iii) how much work was required to move the charge from 10cm to 50cm away from the stationary charge? (iv) what is the final speed of +5mC when it's 50cm away?

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.
