Three forces, ₁, ₂,and ₃,all act on an object,as shown in the figure.The magnitudes of the forces are: F₁ = 80.0 N,F₂ = 60.0 N,and F₃ = 40.0 N.The resultant force acting on the object is given by A)180 N at an angle of 60.0° with respect to +x-axis. B)60.0 N at an angle of 90.0° with respect to +x-axis. C)20.0 N at an angle of 34.3° with respect to +x-axis. D)35.5 N at an angle of 34.3° with respect to +x-axis. E)40.0 N at an angle of 60.0° with respect to +x-axis.

To find the resultant force, we can use the vector addition of the given forces. By adding the forces graphically (using a scale diagram or vector addition), we can see that the resultant force has a magnitude of approximately 35.5 N and makes an angle of approximately 34.3° with respect to the +x-axis. Therefore, the correct answer is D.

Three Forces, 1
