Let the angle between two non-zero vectors `vec(A)` and `vec(B)` be `120^(@)` and its resultant be `vec(C)` then:

Let the angle between two nonzero vectors vec(A) and vec(B) be 120^(@) and its resultant be vec(C) .

If the angle between two vectors vec(a) and vec(b) is zero, then :

If θ is the angle between two non-zero vectors vec a and vec b , then write down the value of sin θ .

If vec a and vec b are two non -zero vectors, then (vec a + vec b) .(vec a - vec b) is equal to

Resultant of three non-coplanar non-zero vectors vec a , vec b and vec c

For non-zero vectors vec(a) and vec(b), " if " |vec(a) + vec(b)| lt |vec(a) - vec(b)| , then vec(a) and vec(b) are-

If vec A+vec B=vec C and the angle between vec A and vec B is 120^(@) , then the magnitude of vec C

If a vector vec a is perpendicular to two non-collinear vector vec b and vec c , then vec a is perpendicular to every vector in the plane of vec b and vec c .
