Question

5. Electric potential difference between two points A and B is 10 V. If A is at higher potential
as compared to B, then work required to be done to move an electron fron
(A) 10 J (B)1.6 x 10-18J (C)48 x 10-21 J (D) 16 J. Awards

Answer 1

Answer:

The answer is (B) 1.6 x 10⁻¹⁸ J

Explanation:

   Given , Potential difference =10V      

       Workdone = Charge x Potential difference

                                 = 1.6 x 10⁻¹⁹ x 10

               Workdone = 1.6 x 10⁻¹⁸ J
