Question

If the magnitude of a charge is half 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.
one-fourth
one-half
two times
four times

Answer 1

Answer:

the electric field strength of this charge is two times the strength of the other charge

Explanation:

Using the relationship between electric field and the charge, which is inversely proportionality. Let the the magnitude of the first charge be Q and the respective electric field be E. It implies that;

E1/E2 = Q2/Q1

E2 = E1 x Q1/Q2

      = E x Q/ (Q/2)

       = 2E
