Question

Calculate the work done in taking a charge of 0.02 c from a to b the if the potential at a is 20v,and that at b is 30v.

Answer 1

Answer: Work Done =0.2 Joules

Explanation: Work done in moving a charge is equal to the product of charge(Q) and change in the potential difference between the two points(V2-V1).

$Q=0.02C\\V2-V1=10V\\W=0.02(10)=0.2$

Here, Work done will be equal to the product of charge (0.02C) and the potential difference between a and b (10V)

(W=Q×ΔV)

W=0.02 C×(30-20)=0.2 Joules
