The potential of the centre of a hollow charged spherical conductor is 1000V. If the radius of the sphere is 10cm ,then charge on the sphere is

$11 \mu C$ $1.1 \mu C$ $ 0.11 \mu C$ $0.011 \mu C$

$0.011 \mu C$

$\text{Potential at the centre of the sphere is } V = \frac{Q}{4\pi \epsilon_0 R} $ $\Rightarrow Q = 4\pi \epsilon_0 RV = \frac{1}{9\times 10^9} 0.1 \times 1000 = 0.011 \mu C$
