Q1:

The resultant of two forces acting at right angles is 5 kgf and if they act at an angle of 60°, it is 37 kgf. The magnitudes of the forces are :

A 2 kgf, 3 kgf

B 3 kgf, 4 kgf

C 4 kgf, 5 kgf

D 5 kgf, 3 kgf.

ANS:B - 3 kgf, 4 kgf

By verification of answers.

Take p=3 kgf, q=4kgf, angle is 60°.

Find out the resultant value,

We are getting the value root 37.
