Text Solution

AI Generated Solution

To solve the problem of calculating the amount of charge to be given to an isolated sphere with a capacitance of 50 pF to raise its potential to \(10^5\) V, we can use the formula that relates charge (Q), capacitance (C), and potential (V): \[ Q = C \times V \] ### Step-by-Step Solution: ...
