The electric field at point p due to a point charge q a distance r away from p has magnitude e. in order to double the magnitude of the field at p, you could the electric field at point p due to a point charge q a distance r away from p has magnitude e. in order to double the magnitude of the field at p, you could double the charge to 2q and at the same time reduce the distance to r/2. reduce the distance to r/4. double the charge to 2q. reduce the distance to r/2. double the distance to 2r.

Double the charge to 2Q

Explanation:

The magnitude of a electric field caused by a charge Q at a distance R can be find by the following expression:

Where K is the Coulomb constant.

As the relationship between the charge and the electric fiel is proportional, by simply doubling the charge, you would double the magnitude of the electric field.

Notice that the distance affects the magnitude of the electric field by the inverse square. So if you half the distance, the magnitude of the field will quadruple.
