Question

Which one of the following sets of horizontal forces can keep a body in equilibrium ?

• A. 12 N, 24 N, and 48 N
• B. 50 N, 75 N and 150N
• C. 35 N, 35N, and 35N
• D. All of the above.

Answer 1

The correct option is A 12 N, 24 N, and 48 N

Solution :- Equilibrium can not be attained

in sets (12N 24N and 48N) and

(50N, 75N and 150 N) as the

sum of first two forces is

less than third force due to

which the net force can never

be zero But in set (35N,

35N and 35N). equilibrium

can be reached if all the

forces are applied at ${120}^{\circ }$ angle

with the closest

option - C is correct.
