A force of (hat(i) + 2hat(j) + 3hat(k))N...

A force of `(hat(i) + 2hat(j) + 3hat(k))N` is acting on a body having position vector `(3 hat(i) + hat(j) + 2hat(k))` in the same frame of reference
In the direction of the moment of force, unit vector is

A

`(hat(i) + 11 hat(j) - 7 hat(k))/(sqrt(171))`

B

`(- hat(i) - 7hat(j) + 5hat(k))/(sqrt75)`

C

`(hat(i) + 7hat(j) - 5 hat(k))/(sqrt75)`

D

`(7 hat(i) - 11 hat(j) + 5 hat(k))/(sqrt(195))`
