Consider three point charges arranged along the xx axis. Chargeq1q1q1 = -4.20 nCnC is located at x=x= 0.240 mm and charge q2q2q2 =2.40 nCnC is at x=x= -0.310 mm . A positive point charge q3q3 islocated at the origin.
a-Calculate the value of q3q3 such that the net force on thispoint charge has a magnitude of 4.80 μNμN
b-Where along the xx axis can q3q3 be placed and the net forceon it be zero, other than the trivial answers of x=+∞x=+∞ andx=−∞x=−∞?
