Two charges of 4 mu C each are placed at...

Two charges of `4 mu C` each are placed at the corners `A` and `B` of an equilaternal triangle of side length `0.2 m` in air. The
electric potential at `C` is `[(1)/(4pi epsilon_(0)) = 9 xx 10^(9) (N-m^(2))/(C^(2))]`

A

`9 xx10^4 V`

B

`18 xx10^4 V`

C

`36 xx10^4 V`

D

`36 xx10^(-4) V`

Text Solution

Verified by Experts

The correct Answer is:
C
`V_C=(K(4+4) xx10^(-6))/(0.2) = (9xx10^9xx8xx10^(-6))/(2xx10^(-1))`
`= 360 xx10^4 ` Volt
