Two forces act at an angle of 1200. If the greater force is 50 N and their resultant is
perpendicular to the smaller force, the smaller force is ________ N.

..Method 1..
Let, the forces are F1 and F2and F1 is the greater force of magnitude 50N
Now, from the figure
Hence, the correct option is (B).
..Method 2..
Let, angle between
forces F1 and F2be 0 (i.e.,0 = 1200) and angle between force F1 and resultant (R) is a.
Now we know that,
Hence, the correct option is (B).
