Consider a plane `pi:vecr*vecn=d` (where `vecn` is not a unti vector). There are two points `A(veca)` and `B(vecb)` lying on the same side of the plane.
Q. If foot of perpendicular from A and B to the plane `pi` are P and Q respectively, then length of PQ be :

A

`(|(veca-vecb)*vecn|)/(|vecn|)`

B

`|(veca-vecb)*vecn|`

C

`|(veca-vecb)xxvecn|`

D
