Question

Two vectors having equal magnitudes A make an angle
O with each other. Find the magnitude and direction of
the resultant.Please explain the solution.
​

Answer 1

Explanation:

V1=A

V2=A

angle=O

magnitude of the resultant vector=F

Now

F=√V1^2+V2^+2V1V2Cos theta

you can find magnitude of the resultant by using this formula

direction

theta=tan-1(V1/V2)

direction of the resultant vector can be found by using this formula.
