You are presented with the quiz "What is likely to exert mutually on an object, making the object remain stationary?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "if two balanced forces act on an object in opposite directions then that object will remain stationary" and "opposites also hold each other in balance and exert mutual control". 

So, what's the best answer to the question?


 

 balanced forces
