​

Answer 1

Answer: A parallel plate capacitor of 5 microfarad charged to 200V is connected across another uncharged capacitor of 15 microfarad their common potential will be 10 mj .

Answer 2

For the parellel plate capacitor we will use formula

$c = 15 + 5$

$c = 20$

common potential will be

$p = \frac{200}{20}$

$p = 10mj$

So the potential will be 10 micro joule
