A conducting sphere of radius 10 cm is given a charge of `+2xx10^(-8)C`. What will be its potential?

A

0.03 kV

B

0.8 kV

C

1.8 kV

D

3.6 kV

Text Solution

Verified by Experts

The correct Answer is:
C
Here, `C=4piepsi_(0)R`
`V=(q)/(C)`
`=(2xx10^(-8))/(4piepsi_(0)R)`
`=(9xx10^(9)xx2xx10^(-8))/(10xx10^(-2))`
`=1.8kV`
