How much work is done by the electric force when a 0.50-C charge is moved from the point (3.0 cm, 2.0 cm) to the point (8.0 cm, 4.0 cm)

This question is incomplete, the complete question is;

How much work is done by the electric force when a 0.50-C charge is moved from the point (3.0 cm, 2.0 cm) to the point (8.0 cm, 4.0 cm)? (the electric potential at 3cm, 2cm is 20V), (the electric potential at 8cm, 4cm is 30V)

work is done by the electric force is 5J

Explanation:

Given that;

Charge C = 0.5 C

Electric potential Ep1 = 20 V

Electric Potential Ep2 = 30 V

work is done by the electric force = ?

now to calculate work is done by the electric force, we say

work is done by the electric force = charge × ( potential drop)

work is done by the electric force = C × ( Ep2 - Ep1 0

work is done by the electric force =  0.50 × ( 30 - 20)

work is done by the electric force = 5J

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.
