Let ' W ' joule be the work done to move an electric charge ' q ' coulomb from a place A , where potential is -5 volt to another place B where potential is ' V ' volt. The value of ' V ' is

Options

  1. AWq -5
  2. Bq w +5
  3. Cw- 5 q
  4. Dw q -5

Correct answer

D. w q -5

Step-by-step solution

The work done W to move a charge q from potential V_A to V_B is given by W = q(V_B - V_A) . Given V_A = -5 , V_B = V , substitution yields W = q(V - (-5)) = q(V + 5) . Solving for V , we have W q = V + 5 , and thus V = W q - 5 . This corresponds to option D .
