101. A hollow cylinder has a charge q coloum at the 103. In the figure shown here, A is a conducting sphere
centre. If ϕ is the electric flux in units of voltmeter and B is a closed spherical surface. If a −q charge is
associated with the curved surface B, the flux linked placed at C near A, then the electric flux through the
with the plane surface A in units of voltmeter will be closed surface B is
