The sum of the magnitudes of two forces acting at point is 18 and the magnitude of their resultant is 12. If the resultant is at 90 ° with the force of smaller magnitude, what are the, magnitudes of forces
Text Solution
Verified by ExpertsThe correct answer is:
C
Let P be the smaller force and Q be the greater force then according to problem –
P + Q = 18 ......(i)
.......(ii)
.......(iii)
By solving (i), (ii) and (iii) we will get 
and
