What formula gives the strength of an electric field, E, at a distance from a known source charge? E = E = E = E =

Answer;

E = kQ/d²

Explanation;

The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.

Therefore; electric field strength is given by the formula;

E = kQ/d²;

where E is the electric field strength,

Q is the quantity of charge on the source charge and

d is the distance of separation from the source charge
