If M denotes the mid-point of the line joining `A(4hati+5hatj-10hatk)` and `B(-hati+2hatj+hatk)` then equation of the plane through M and perpendicular to AB is:

`vecr*(5hati+3hatj-11hatk)-135/2=0`

`vecr*(3/2hati+7/2hatj-9/2hatk)+135/2=0`

`vecr*(4hati+5hatj-10hatk)+4=0`

`vecr*(-hati+2hatj+hatk)+4=0`
