Given ` vec A+ vec B+ vec C + vec D=0`, can the magnitude of ` vec A + vec B + vec C` be equal to the magnitude of vec D` Explain.

Given vec A+ vec B+ vec + vec D=0 , can the magnitude of vec A + vec B + vec C be equal to the magnitude of vec D Explain.

Three vectors vec A,vec B and vec C are related as vec A+vec B=vec C .If vector vec C is perpendicular to vector vec A and the magnitude of vec C is equal to the magnitude of vec A, what will be the angle between vectors vec A and vec B .

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

Two vectors vec A and vec B have equal magnitudes.If magnitude of (vec A+vec B) is equal to n xx of the magnitude of (vec A-vec B) then the angle between vec A and vec B is :

Two vectors vec A and vec B have equal magnitudes. If magnitude of vec A-vec B is equal to (n) times the magnitude of vec A-vec B , then angle between vec A and vec B is ?

Give vec A + vec B+ vec C + vec D =0 , which of the following statements are correct ? (a) vec A, vec B ,vec C abd vec C must each be a null vector. (b) The magnitude of ( vec A + vec C) equals the magnitude of ( vec B + vec D0 . ltBrgt (c ) The magnitude of vec A can never be greater than the sum of the magnitude of vec B , vec C and vec D . ( d) vec B + vec C must lie in the plance of vec A + vec D. if vec A and vec D are not colliner and in the line of vec A and vec D , if they are collinear.

Two vectors vec A and vec B have equal magnitudes.The magnitude of (vec A+vec B) is 'n' times the magnitude of (vec A-vec B).The angle between vec A and vec B is:

[[vec a + vec b-vec c, vec b + vec c-vec a, vec c + vec a-vec b is equal to

[vec a + vec b, vec b + vec c, vec c + vec a] = 2 [vec a, vec b, vec c]

[vec a, vec b + vec c, vec d] = [vec a, vec b, vec d] + [vec a, vec c, vec d]
