If vectorA+ vectorB= vectorA=vectorB then find angle btwn vectorA and vectorB

Question

Arun · Answer

Dear student The angle between A and B is not defined. Let vector A = a ; vector B = b. a+b = a-b, 2b = 0(null vector). Hence b is a null vector and a is any possible vector. The catch is that the null vector doesn't have a well defined direction, and hence you cannot find the angle between a and b.
