An electron is moved from point A to point B in a uniform electric field and gains 4.66×10-15 J of electrostatic potential energy. Calculate the magnitude of the electrostatic potential difference between the two points. (in V)

2.9125 x 10⁴ V

Explanation:

The electrostatic potential difference (ΔV) between two points, say A and B, is denoted by - and is the quotient of the change in the electrostatic potential energy (Δ) of a charge Q moved from A to B, and the charge. i.e

ΔV = - = Δ / Q               ------------(i)

From the question;

Δ = 4.66 x 10⁻¹⁵J

Q = charge of an electron = -1.6 x 10⁻¹⁹C

Substitute these values into equation (i) as follows;

- = (4.66 x 10⁻¹⁵) / (-1.6 x 10⁻¹⁹)

- = -2.9125 x 10⁴ V

| - | = 2.9125 x 10⁴ V

Therefore, the magnitude of the electrostatic potential difference between these two points is 2.9125 x 10⁴ V

the reason is because the moon has some form of gravity, and that gravity pulls the ocean tides.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
