Answer 2

Answer:

$\huge\fbox\colorbox{pink}{⛄ANSWER⛄}$

In this question we have been given that 10Megajoule of work is done in moving a charge of 10Uc , potential difference in this case is not known, we have to calculate it.

In this question :

Work done = 10Mj = 10^ -3J

Total charge = 10Uc

Potential difference = v = ?

Now, after inputting the known values in the equation we get :-

$= > v \: = \frac{10 \times {10}^{ - 3} }{10 \times {10}^{ - 6} }$

$= > v \: = 1000$

Therefore potential difference of system is 1000V.

Hope my solution helps you.
