Santino wanted to get a new iPhone this weekend. At the store, there was only one iPhone left. He saw four people pulling on the iPhone in different directions. Roger was pulling North with 10 N of force, Garret was pulling East with 16 N of force, Andrea was pulling South with 10 N of force, and Mariah was pulling West with 27 N of force. What is the magnitude and direction of the net force on the iPhone?
