HOPE YOU WILL BE FINE
Today we are going to study force vector in 2D
We will solve a numerical of force vector
Here we have to find FR i-e resultant force
 
 
the angle from the positive x-axis to Fr
we have to find this theta
so first we must know there magnitudes
 
 
 
 
 
 
 
we will contruct a parallelogram
 
 
 
 
 
 
 
 
 
Now in triangular form
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
we can first find this region
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
so thankyou
