Ans) D) -7.6N
See magnitude of force along x direction will not depend on forces along y - direction
So we would only consider forces along x direction
Now , net force acting along positive direction = -24 + 20cos35°
As only cos component is acting along x-direction.
Putting value of cos35° we would get,
Net force = -24 +16.4N
= -7.6 N
Hope it helps!!!
