two forces whose magnitude are in the
ratio of 3:5 give a resultant of 35 N. If the
angle of inclination be 60degre Calculate
magnitude of each force.​

Answer 1

Answer:

P=15 N & Q=25 N

Explanation:

R= root over of [(P)^2 +(Q)^2+ 2PQcos60°]

=>35N= root over of [(3f)^2+(5f)^2+ 2×3f×5f×cos60°]

=> 35N= root over of (49 f^2)

=>35N=7f

=> f= 5N

P=3× 5N= 15N & Q=5× 5N=25N
