Two negative point charges (q= -2.6 x 10-19 c and q2= -6.4 x 10-19 c) and a proton (P) lie on a straight line with separation D1=1 centimeter and D2 = 2 centimeter, proton carries one elemental charge,
a) Find what is the force on the proton due to q1?
b) Find what is the force on the proton due to q2?
c) Determine what is the net force on the proton?
