Two forces, and , are acting at a point, where the magnitude of is
N more than that of . If their resultant is perpendicular to the line
of action of and has a magnitude of N, find the magnitude of each force.
Since is N more than , therefore
Use the above and substitute.
For the above equation to be equal to , the denominator
must be equal to zero.
Substitute all into the relation for magnitude and rearrange to
get each force.
