Question

There is an electric field E in x-direction. If the work done on moving a charge of 0.2 C 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) 5 N/C

(b) 20 N/c

(c) √3 N/C

(d) 4 N/c

Answer 1

Correct option  (b) 20 N/c

Explanation:

Charge (q) = 0.2 C; Distance (d) = 2 m; Angle 60° and work done (w) = 4J

Work done in moving the charge (W)
