The electric field surrounding point charges are radial and the field strength is equal to kQ/r2 at a distance r from Q.The electric potential near a point charge is V = kQ/r, which is negative if Q is negative.
E is a vector but V is scalar. A negative E indicates the field is acting towards a negative charge. A negative V indicates the value of the potential is less than zero. E varies with distance more sharply than V does.
