Question

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

Answer 1

Answer:

The work done by the force is 6μJ

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

$W=-30\times10^{-9}\times(-70-130)$

$W=0.000006\ J$

$W=6\times10^{-6}\ J$

$W=6\ \mu J$

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