The insulation property of air breaks down at $3 \times 1 0^{6} V / m$ . The maximum charge that can be given to a sphere of diameter $5 m$ is nearly

Options:

Answer:

Solution:

Maximum electric field, $E_{mix} = \frac{1}{4 π ε _{0}} \frac{Q _{m a x}}{R ^{2}}$ $3 \times 1 0^{6} = \frac{9 \times 1 0 ^{9} \times Q _{m a x}}{2.5 \times 2.5} or Q_{m a x} = \frac{3 \times 1 0 ^{6} \times 2.5 \times 2.5}{9 \times 1 0 ^{9}} = 2 \times 1 0^{- 3} C$
