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