Charge of 1`mu`C each is placed on the five corners of a regular hexagon of side 1m. The electric field at its centre is _____ N/C

A

`5/6 xx 10^(-6) K`

B

`5 xx 10^(-6) K`

C

`6/5 xx 10^(-6)K`

D

`10^(-8) K`

Text Solution

Verified by Experts

The correct Answer is:
D
Electric field at centre due to five charges is equal to E.F due to one charge
`E = (KQ)/(r^2)`
`= (K xx (10^(-6)))/(1^2) = 10^(-6)K`
