at a distance of 1.0 m from a point charge, the electric field is 40 J/C. What is the electric field at a distance of 2.0 m from the point charge?
The Attempt at a Solution
so, i understand that the elecric field should be = charge/distance(squared).
so I did:
40/(2^2) = 10 J/C
Is this correct or am i missing something? thanks
