Multiple choice

If 2.5 × 10–6 coulomb of charge from point D to point E, in an electric field requires 6.3 × 10–4 joule of work. Calculate potential difference between points D and E.

  1. 2.5 × 10–6 V

  2. 2.5 × 10–2 V

  3. 0.396 × 10–2 V

  4. 15.75 × 10–6 V

  5. 15.75 × 10–2 V

C Correct answer
Explanation

V=W/q, work and charge. Therefore 6.3 × 10-4 / 2.5 × 10-2= 0.396× 10–2 V.
