In a region of space a uniform electric field E=(2i^+3j^)V/m  exists. A(3, 0)m and B(0, 2)m are two points. Then potential difference between A and B is

a
1 V
b
5 V
c
Zero
d
7 V

detailed solution

Correct option is C

Position vector of A relative to B is, rA/B→=rA→-rB⇀=(3i^-2j^)m∴VA-VB=-E→.rA/B→=-(2i^+3j^).(3i^-2j^)volt =6-6=0
