Find the work done "by" the electric field on a positively charged point particle with a charge of 2.1x10^-6 c as it is moved from a potential of 15.0 v to one of 8.0 v. (include the sign of the value in your answer.)

Answer

Work done will be and it will be positive

Explanation:

We have given charge

We have to find work done in moving the charge from 15 volt to 8 volt

Let

So potential difference

We know that work done , here Q is charge and V is potential difference

So work done

It will be positive work done because work is done in moving charge from higher potential to lower potential
