A charged spherical conductor has a surface density of $0.07C \;cm^{–2}$. When the charge is increased by $4.4\;C$, the surface density changes to $0.084 \;C cm^{–2}$. Choose the right option/s. (A) the initial charge of the spherical conductor is $22\;C$ (B) the capacitance of the spherical conductor $5.56 \times10^{–12}F$ (C) the initial charge of the spherical conductor is $33\;C$ (D) the capacitance of the spherical conductor $6.56 \times 10^{12}F$
