The number of lines of force starting from a point charge of `10muC` in vacuum are

A

`1.2xx10^(6)Nm^(2)//C`

B

`1.3xx10^(6)Nm^(2)//C`

C

`1.13xx10^(6)Nm^(2)//C`

D

`2.3xx10^(6)Nm^(2)//C`

Text Solution

Verified by Experts

The correct Answer is:
C

`N=q/epsi_(0)=(10xx10^(-6))/(8.85xx10^(-12))=1.13xx10^(6)Nm^(2)//C`.
