Isthe magnitude of `(vec A + vec B)` same asthat of `(vec B + vec A)` ?

Are the magnitude and direction fo (vec A-vec B) . same as that of (vec A-vec B) ?

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:

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 ?

If vec A+vec B=vec C , then magnitude of vec B is vec C-vec A sqrt(vec C*vec A-vec B*vec A) sqrt(vec C*vec B-vec A*vec B) C-A

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 :

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.

If the magnitudes of vec(a) xx vec(b) equals to vec(a). vec (b) , then which one of the following is correct ?

Consider the following statements: 1. The magnitude of vec(a) xx vec(b) is same as the area of a triangle with sides vec(a) and vec(b) . 2. If vec(a) xx vec(b)=vec(0) where vec(a) ne 0. vec(b) ne 0 then vec(a) = lamda vec(b) which of the following statements is/are correct?

Two vectors vec(A) and vec(B) have precisely equal magnitudes. For the magnitude of vec(A) + vec(B) to be larger than the magnitude of vec(A)-vec(B) by a factor of n , what must be the angle between them?
