Question

14. What should be the position of charge q = 5uC for it to be in equilibrium on the line joining
two charges 91 = 4uC and 92= 16C separated by 9 cm. Will the position change for any
other value of charge q?
15. Two-point charges 4e and e each, at a separation r in air, exert force of magnitude F. They
are immersed in a medium of dielectric constant 16. What should be the separation between
the charges so that the force between them remains unchanged.
16. Two capacitors of capacitance 10 F and 20 F are connected in series with a 6V battery. If E
