Problem

There is a uniform electric field in the positive

y

-direction. If the work done by external agent in moving a charge of 0.2 C through a distance of 2 metre slowly along the line making an angle of

60^\circ

with the positive

X

-direction in anti-clockwise sense is 4 joule, then the magnitude of

E

is: (a)

\sqrt{3}

N/C (b) 4 N/C (c) 5 N/C (d)

\frac{20}{\sqrt{3}}

N/C
