Vectors are inclined at an angle θ = 60o.
Let be unit vector such that If the angle between
If the force represented by is acting through the point , then its moment about the point (1, 3, 1) is
The moment of the couple formed by the force acting at the points (9, –1, 2) and (3, –2, 1) respectively, is
be three vectors. Then scalar triple product is equal to
If are three vectors such that then
x + y + z =
