70. Two point charges (Q1 = 5 nC and Q2 = −8 nC) are located in vacuum at a distance l = 10 cm. Determine the force F that acts on the charge Q0 = 1 nC, placed at a point located on a straight line connecting the charges and remote at r1 = 4 cm from the first charge and at r2 = 6 cm from the second charge.
