If the circumference of a sphere is 2 m, then capacitance of sphere in water would be

A

2700 pF

B

2760 pF

C

2780 pF

D

2800 pF

Text Solution

Verified by Experts

The correct Answer is:
D
Given `2pi R = 2 implies R =1/pi`
For shere `C = 4pi epsilon_0KR`
`implies C=1/(9xx10^9)xx1/pi xx80 ` [For water K = 80]
`implies C = 2828.28 PF` (approx).
