Verified by Toppr

Since the charged conductor induces opposite charge on the near face of the isolated conductor, which moves the charges of the conductor towards it making it draw more charge from the source where it is connected. Hence the capacity of a conductor is affected due to the presence of an uncharged isolated conductor.
