Question

the Resultant force of two equal parallel Sorces recting an opposite direction in the Same line of action is a) Fnet - F1+ F2 b)Fnet= F2-F1 c)Fnet - F2 + F1 d) Fnet = 0​

Answer 1

Answer:

From figure 1, net force F' =F

1

−F

2

From figure 2 net force F" =F

=27

Factors of F = 27 are 1, 2, 7, 3, 9

⇒ If F
