Answer:
The net force acting on the body, F = 11 N
Step-by-step explanation:
Given data,
The force acting on the body, f = 5 N
Another force acting on the body, f' = 6 N
The direction of both forces is in the same direction.
The net force is given by the resultant vector,

(∵ θ = 0)

F = f + f'
= 5 N + 6 N
= 11 N
Hence, the net force acting on the body, F = 11 N
