The potential at a point due to charge of `5xx10^(-7)C` located 10 cm away is

A

`3.5xx10^(5)V`

B

`3.5xx10^(4)V`

C

`4.5xx10^(4)V`

D

`4.5xx10^(5)V`

Text Solution

Verified by Experts

The correct Answer is:
C
Here, `q=5xx10(-7)` C , r=10 cm =0.1 m
Potential, `V=1/(4piepsilon_0) q/r = (9xx10^9 xx 5 xx10^(-7))/0.1=4.5xx10^4` V
