Question

The radius of earth is 6400 km, then the
capacitance of earth is
(a) 711 uF
(b) 611 uF
(c) 811 uF
(d) 511 uF​

Answer 1

Answer:

(a)711 uF

Solution

$\huge\green{\boxed{Hey\:Mate}}$

Capacitance C=Q/V

$c \: = \frac{6400 \times 1000}{9 \times {10}^{9} }$

C = 711 micro-farad

Hope this will help uh!!
