Question

How much work is done by the force that moves the charge?

Answer 1

The work done by the force is 6μJ

Step-by-step explanation:

Suppose, A 30 nC charge is moved from a point where V₁ = 130 V to a point where V₂ = -70 V.

We need to calculate the work done by the force

Using formula of work done

`W=-q\Delta V`

Where, q = charge

`\Delta V` =potential difference

Put the value into the formula

`W=-30*10^(-9)*(-70-130)`

`W=0.000006\ J`

`W=6*10^(-6)\ J`

`W=6\ \mu J`

Hence, The work done by the force is 6μJ.
