Solve the following question given below:

Question: Two forces, FA and FB, act on an object such that the object accelerates in the y-direction. FA is 150 N and is 55.0o from the positive x-axis.

Part A: What is the magnitude of FB if FB is 30o above the negative x-axis?

Part B: What third force (magnitude and direction) is necessary if you wish to keep the object from accelerating? Draw a diagram to show your reasoning.

I need expert help to solve the above question.
