A uniform electric field to 100 Vm^(-1) ...

A uniform electric field to 100 `Vm^(-1)` is directed at `60^@` with the positive x-axis as shown in figure. If OA= 2 m, the potential difference `V_O - V_(A)` is

A

`-50V`

B

`50V`

C

`100 V`

D

`-100V`

Text Solution

Verified by Experts

The correct Answer is:
D

`OB=OAcos60^(@)=2xx(1)/(2)=1m`
`V_(B)-V_(O)=E(OB)=100xx1=100V`
`V_(A)-V_(O)=100V[becauseV_(B)=V_(A)]`
`V_(O)-V_(A)=-100V`
