Question

The resultant of two forces acting at right angles is 5 kgf and if they act at an angle of 60&#176;, it is 37 kgf. The magnitudes of the forces are :-A-2 kgf, 3 kgfB-3 kgf, 4 kgfC-4 kgf, 5 kgfD-5 kgf, 3 kgf.-B-3 kgf, 4 kgf

APTITUDE CRACK · Accepted Answer

B 3 kgf, 4 kgf First acting 90 angle then = 5^2=p^2 +Q^2. If acting 60 then=37=p^2+q^2+2pq cos 60 =25+pq. Then pq=12. solve it.
