[" If "vec A+vec B=vec C," then magnitude of "vec B],[" is "]

If vec A=vec B+vec C, and the magnitude of vec A,vec B and vec C are 5,4 and 3 units respectively.the angle between vec A and vec C is

If vec(A)=vec(B)+vec(C ) , and the magnitudes of vec(A) , vec(B) , vec(C ) are 5,4, and 3 units, then the angle between vec(A) and vec(C ) is

If vec(A)=vec(B)+vec(C ) , and the magnitudes of vec(A) , vec(B) , vec(C ) are 5,4, and 3 units, then the angle between vec(A) and vec(C ) 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 vec(A)=vec(B)+vec(C) and the magnitude of vec(A), vec(B) and vec(C) are 5, 4, and 3 units respectively the 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.

Let vec a, vec b and vec c of magnitudes 3,4 and 5 repectively. If vec a is perpendicular to (vec b + vec c), vec b is perpendicular to (vec c + vec a) and vec c is perpendicular to (vec a + vec b) , then the magnitude of vec a + vec b + vec c is

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

For any two vectors A and B, if vec(A).vec(B) = |vec(A) xx vec(B)| , the magnitude of vec(C ) = vec(A) + vec(B) is equal to :

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 .
