Question

A charge of +3.1 × 10-16 coulombs is moved between two points, resulting in a potential difference of +15 volts. What is the magnitude of the work done on that charge?

2.3 × 10-15 joules

4.7 × 10-15 joules

3.1 × 10-15 joules

9.2 × 10-15 joules

Answer 1

Hope this helps you.

Answer 2

Work done,
`W=4.65* 10^(-15)\ J`

Step-by-step explanation:

It is given that,

Magnitude of charge,
`q=3.1* 10^(-16)\ C`

Potential difference between two points,
`\Delta V=+15\ Volts`

We have to find the magnitude of work done on that charge. The relationship between the work done and the potential difference is given by :

`\Delta V=(W)/(q)`

`W=15\ V* 3.1* 10^(-16)`

`W=4.65* 10^(-15)\ J`

or

`W=4.7* 10^(-15)\ J`

Hence, the magnitude of work done on the charge is
`4.65* 10^(-15)\ J`
