Question

The electric force generated by two point charges separated by Distance A is 4 times greater than the electric force generated when separated by distance B. How does Distance A compare to Distance B?

A. Distance A is longer by a factor of 2

B. Distance A is longer by a factor of 4

C. Distance A is shorter by a factor of 2

D. Distance A is shorter by a factor of 4

Answer 1

The answer is C. Distance A is shorter by a factor of 2.

Electric Force = 1/r^2. Hope this helps!
