Two points(q1 and q2) are located on the positive x-axis and one charge(q3) is located on the negative x-axis of the co-ordinate systeem. q1=2.0 nC is 150cm from the origin, charge q2=2.5nC is 300cm and charge q3= 3.0 nC and is 250cm. What is the total force exerted by this charges on the charge q0=4.0nC located on the origin?
