2 points A and B are at electric potentials 10 V and 100 V respectivel

1.	2 points A and B are at electric potentials 10 V and 100 V respectively. A charge q is taken from A to B and 18 Joule of work is done. The value of q is (1) 2 Coulomb (2) 0.2 Coulomb (3) 20 Coulomb (4) 0.02 Coulomb
Answer» (2) 0.2 Coulomb As, W = VQ ∴ Q = 18 / 90 = 0.2 c
