Question

The condition under which the vector
a-b is parallel to b is:
(A) a parallel to b
(B) a perpendicular to b
(C) magnitude of a equal to magnitude of b
(D) magnitude of a not equal to magnitude of b

​

Answer 1

hi dear here iš ur answer

Parallel and Perpendicular Vectors. Two vectors A and B are parallel if and only if they are scalar multiples of one another. A = k B , k is a constant not equal to zero. Two vectors A and B are perpendicular if and only if their scalar product is equal to zero.

hope it is help full
have a nice day
