Question

PLEASE ANSWER THIS FAST
The resultant of 2 vectors at an angle 120 is perpendicular to smaller vector if the larger vector is of magnitude 10 units find the resultant and smaller vector?
​

Answer 1

Answer:

5√3 and 5

Explanation:

Resultant is perpendicular to smaller vector

Suppose smaller vector is along x and resultant is along y

Then x componets of two vector must cancle out

10cos120+smaller vector=0

Smaller vector=5

Resultant=y component of larger vector

=10sin120=5√3
