JEE Main 2015 (11 Apr Online)

Question

An electric field E→=25 i^+30 j^ N C-1 exists in a region of space. If the potential at the origin is taken to be zero then the potential at x=2 m, y=2 m is:

Correct answer
A-110 J C-1

Step-by-step explanation

∵∆V=-E→.∆r→

V-0=-25i^+30j^. 2i^+2j^

=-50+60

V=-110 volt=-110 J C-1
