Question

What is the workdone to bring a charge of 10 mc from infinity to a point having potential 10 V

Answer 1

$\mathtt{ \huge{ \fbox{Solution :)}}}</strong></p><p><strong>$

Given ,

• Charge = 10 mili coulomb or (10)^-2 C
• Potential difference = 10 V

We know that , potential difference is defined as the amount of work done required to bring a charge from infinity to particular point

$\large \mathtt{ \fbox{V = \frac{work \: done}{charge} }}$

Thus ,

Work done = 10 × (10)^-2

Work done = (10)^-1

Hence , the required value of work done is (10)^-1 joule
