Question

if angle between A vector and B vector is 60° and magnitude of vectors are same and equal to 5 unit than calculate magnitude of resultant vector and angle between A vector and R vector​?

Answer 1

Answer:

5√3

Explanation:

we know when magnitude of both vectors are equal then:

r=2acos O/2

= 2.5.cos 60/2

= 10.√3/2
