A

`q/(hati.overset(rarr)n)`

B

`(hati.overset(rarr)n)/q`

C

`q/(abs(overset(rarr)n)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
1
`vecr.vecn=q`
Let , intercept made by the plane (1) on the x-axis is `x_(1)`
`implies` plane (1) passes through it
`x_(1),hati.vecn =q implies x_(1) =(q)/(hati.vecn)`
