Question

There two conductors A and B having charges +15 − 25 respectively. Both are made to touch each

other and then separated; now conductor A has a charge of−3 . What is the value of charge on conductor B?​

Answer 1

Answer:

-7 C.

CONCEPT USED

1. charge is always conserved
2. So, sun of total charges initial = total charge finally.

that's why ,

15 - 25 = -3 + charge on B

=> Charge on B = -7 unit
