Question

An electric field =10x exists in a certain region of space. Then the potential difference V = Vo – VA, where Vo is the potential at the origin and VA is the potential at x = 2 m is

Answer 1

Assume that an electric field

→

E

=30x2

ˆ

i

exists in space. Then the potential difference VA−VO, where VO is the potential at the origin and VA the potential at x=2 m is (A) 120 J (B) −120 J (C) −80j (D) 80 J
