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)    3 N/C

        (b)    4 N/C

        (c)    5 N/C

        (d)    20 N/C

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) 3 N/C

(b) 4 N/C

(c) 5 N/C

(d) 20 N/C

Amit Saxena · Answer

(d) Charge (q) = 0.2 C; Distance (d) = 2m; Angle q = 60&deg; and work done (W) = 4J. Work done in moving the charge (W)

Ajeet Tiwari · Answer

hello student, Work done,W=F.r=Frcos&theta;=qErcos&theta; or1=0.2&times;E&times;2cos60 orE=0.2&times;2cos601​=1/0.2&times;2(1/2)​=5N/C hope it helps thankyou

Yash Chourasiya · Answer

Dear Student We Know that F = qE W = qE&Delta;lcos&theta; W = qE2 cos(60 ∘ ) 4 = 0.2E*2*(1/2) E = 20 NC -1 I hope this answer will help you. Thanks & Regards Yash Chourasiya
