Question

if four forces F,2F,3F,4F are acting on the sides of the square taken in order.Then their resultant is given as​

Answer 1

The resultant of 4 vectors in X, Y direction are:

resultant in X direction is  

3  

P

−  

P

=2  

P

      (in -ve x direction)

In y direction is

4  

P

−2  

P

=2  

P

     (in +ve y direction)

So, the net resultant force vector is  

R

→

=2  

P

→

+2  

P

→

 

angle between both vectors is 90

So magnitude of resultant is 2  

2

​  

P  in direction of 45  

0

 from positive y axis in IV quadrant.
