Question

the resultant of two vectors p and q is perpendicular to vector p and its magnitude is half that of vector q what is the angle between vector p and q

Answer 1

Answer:

answer ; cos inverse ( - p / q )

Explanation:

resultant of p and q is perpendicular to p

(p + q ). p = 0

p² + q.p =0 ; p² +qpcosθ = 0 ;

cosθ = - p /q ;

this is your answer :)
