The figure shows two forces, each of magnitude 4.6 N, acting on an object.
The angle between these forces is 40, and they make equal angles above and below the horizontal. What third force will cause the object to be in equilibrium (acceleration equals zero)?
A) 8.6 N pointing to the right
B) 7.0 N pointing to the right
C) 4.3 N pointing to the right
D) 3.5 N pointing to the right

A) 2.5 m/s2
B) 2.0 m/s2
C) 1.5 m/s2
D) 1.0 m/s2
