Expert Solution
Step 1

When two items with an excess of one type of charge are near enough together, they repel each other. When two positively charged and negatively charged objects are in close contact, they attract one other.

 The electric field produced by a charge Q at a location r can be expressed as,

E=Q4π°r2r^

Where, r is the unit vector.

So, it is seen that E depends on charge of the positive charge, distance between electron and positive charge.

For force,

F= q * E

So, force depends on charge of electron, charge of the positive charge, distance between electron and positive charge.
