There is an electric field E in x-direction. If the work done on moving a charge of `0.2C` through a distance of 2 m along a line making an angle `60^@` with x-axis is 4 J, then what is the value of E?

A

`sqrt(3) NC^-1`

B

`NC^-1`

C

`NC^-1`

D

`20 NC^-1`

Text Solution

Verified by Experts

The correct Answer is:
d

`F = qE`
`W = q E xx 2 cos 60^(@)`
or `4 = 0.2 E xx 2 xx (1)/(2)` or `E = 20 NC^-1`.
