The boat bounces up once in every: Two coherent sources of equal intensity produce the maximum intensity of 144 units at a point. (b) To what location should the point at 20 cm be moved to increase this potential difference by a factor of two? The absolute permeability assigned to a vacuum is ________. The potential difference between points A and B in the given uniform electric field is : A Ea B E (a 2+b 2) C Eb D (Eb/ 2) Hard Solution Verified by Toppr Correct option is C) Was this answer The SI unit of potential difference is volts. The potential difference across the plates is: Two insulating plates are both uniformly charged in such a way that the potential difference between them is ${V_2} - {V_1} = 20V$.
