Question

A body is acted upon by two forces F1 = 6 N and
F2 = 4 N. If net force acting on body is 10 N, then
which of the following is true?
(1) F1 and F2 are in the same direction
(2) F1 and F2 are in the opposite directions
(3) F1 and F2 are perpendicular to each other
(4) F1 and F2 are inclined at an angle of 60°

Answer 1

F1and F2 are in the same direction . when two ar more then two forces act on a body in the same direction then the net force is sum of all forces acting on the body
F1=6N,F2=4N
net force = 6N+4N
10N
