Question

If the magnitude of a charge is twice as much as another charge, but the force experienced is the same, then the electric field strength of this charge is _____ the strength of the other charge.

A) 1/4
B) 1/2
C) 2 Times
D) 4 Times

Answer 1

B

Step-by-step explanation:

Using the relationship between E and Q.

Let the magnitude of the frist charge be Q and the respective electric field be E.

E1/E2 = Q2/Q1

E2 = E1 x Q1/Q2

= Ex Q/2Q

= E/2
