In the figure take q1 = 22uC and q2 = 20u. The force on q_1 points in the - x direction, What is the magnitude of the force on q_1? I don't know where to start, can someone help me?

You have to know position of q2, then use coulomb's law.
the postion of q2 is 2. Do i have to include q3 to find the magnitude of q1?
You don't mention any q3.
