Mohan, Rehana, and Sohan are pushing a heavy box, as shown in the given figure. Mohan is applying twice the force as compared to that being applied by Sohan, while Sohan is applying twice the force as compared to that being applied by Rehana.

If Sohan is applying a force of magnitude 60 N, then the resultant force on the box will be

Given that;

Force applied by sohan=60N

Force applied by Rehana=60/2=30N

Force applied by Mohan=2 x 60=120 N

Force applied by Sohan and rohana in a direction opposite to direction of force applied by mohan=60+30=90N

Resultant force=120-90=30N

Mohan= 120N

Sohan= -60N

Rehana= -30N

force= 120-90

=30N
