Electric Charges and Fields - Result Question 29

29. From a point charge, there is a fixed point A. At A, there is an electric field of 500V/m and potential difference of 3000V. Distance between point charge and A will be

(a) 6m

(b) 12m

(c) 16m

(d) 24m

Show Answer

Answer:

Correct Answer: 29. (a)

Solution:

  1. (a) Given : Electric field (E) =500V/m and potential difference (V)=3000V.

We know that electric field

(E) =500=Vd or d=3000500=6m

[where d= Distance between point charge and A]
