In the previous problem , if the shells `A` and `C` are at the same potential , then

Options

A. `a + b = c`
B. `a = b + c`
C. `a - b = c`
D. `a = b - c`

Answer

1

Explanation

`V_(A) = V_(C)`
`(sigma)/(in_(0)) (a - b + c) = (sigma)/(in_(0)) ((a^(2) - b^(2))/(c ) + C)`
`a - b = ((a + b) (a - b))/(c )`
`c = a + b`
