A potential difference of 10.0 volts exists between two points, A and B, within an electric field. What is the
magnitude of charge that requires 2.0 x 10-2 joule of work to move it from A to B?
1. 5.0 x 10^2 C
2. 2.0 x 10^-1 C
3. 5.0 x 10^-2 C
4. 2.0 x 10^-3 C

Respuesta :

Answer:

answer is 4

Explanation:

The charge that is moved is required.

The magnitude of charge moved is option 4. [tex]2\times 10^{-3}\ \text{C}[/tex]

Potential difference

V = Potential difference = 10.0 V

W = Work done = [tex]2\times10^{-2}\ \text{J}[/tex]

q = Magnitude of charge

When work done on moving a charge is divided by the potential difference we get the magnitude of the charge that is moved.

The charge of an object is the result of an excess or a lack of positive or negative charges on a body.

So, the magnitude of charge is given by

[tex]q=\dfrac{W}{V}\\\Rightarrow q=\dfrac{2\times 10^{-2}}{10}\\\Rightarrow q=2\times 10^{-3}\ \text{C}[/tex]
