Question

An object under the action of three force f1, f2, f3 is in equilibrium. If the direction of f2 is reversed without changing its magnitude, the net force on the object becomes:

Answer 1

Hello Mate!!☺

Fnet = 0

=> F1 + F2 + F3 =0

=> F1 -F2 + F3 =0

=> F2 = F1 + F3

Hope this helps you !!
