here total charge bounded by cube is q=2c According to gauss' law total issued flux by faces={1/,€o K}×q =4π×9×10^9×2 =2.26×10^11 This is the total flux now flux issues by only one face then we know that a cube has six faces hence divide total flux by 6 i.e. Flux issued by one face={2.26×10^11}/6 =0.3766×10^11 volt-meter I hope this is right. Please check and say.

What do you mean by conservation of charge?

Posted by Jashan Sethi 6 years, 5 months ago

CBSE > Class 12 > Physics

2 answers

Yogita Ingle 6 years, 5 months ago

Conservation of charge means charge can neither be created, nor be destroyed. It is just passed from one body to another.

Like when we rub two bodies, say a silk cloth and glass rod, then the charged gained by the silk cloth will be equal in magnitude with that loosed by the glass rod.
