Question

If 1200 J of work must be done to move an electric charge equal to 6 C from a potential of -20 V to V volts, then the value of V is

Answer 1

Answer:

180 V

Explanation:

Work = Potential difference x Charge

Potential difference = Vf - Vi

                                 =V - (-20)

                                 = V + 20

Charge = 6C

Work = 1200 = (V+20) x 6

V = 200 - 20

V = 180 V
