A charge q moves from point A to point B. The potential energy of the charge at point A is 5.3 _ 10-10 joules and at point is B is 3.1 _ 10-10 joules. If the kinetic energy of the charge at point A is zero, what is the kinetic energy at point B?
Select one of the options below as your answer:

A.
8.4 _ 10-10 joules
B.
5.3 _ 10-10 joules
C.
3.1 _ 10-10 joules
D.
2.2 _ 10-10 joules
E.
1.5 _ 10-10 joules

The change in electric potential energy will be converted to kinetic energy; thus:
K.E = 5.3 x 10⁻¹⁰ - 3.1 x 10⁻¹⁰
K.E = 2.2 x 10⁻¹⁰ Joules
Option D is correct.

The kinetic energy at point B will be 2.2 x 10⁻¹⁰ Joules. Option D is correct.

What is the charge?

When the matter is put in an electromagnetic field, it has an electric charge, which causes it to experience a force. A positive or negative electric charge can exist.

Charges that are similar repel each other, whereas charges that are dissimilar attract each other. The term "neutral" refers to an item that has no net charge.

The change in electric potential energy is transferred to kinetic energy, resulting in:

K.E = 5.3 x 10⁻¹⁰ - 3.1 x 10⁻¹⁰

K.E = 2.2 x 10⁻¹⁰ Joules

The kinetic energy at point B will be 2.2 x 10⁻¹⁰ Joules.

Hence, option D is correct.
