Q.2 The charged plates of a capaciter attract each other, so to pull the plates farther apart requires work by some external force.What becomes of the energy added by this work? Explain.
Q.3 The two plates of a capacitor are given charges (plus,minus Q) . The capacitor is disconnected from the charging device so that the charges on the plates can not change, and the capacitor is immersed in a tank of oil. Does the electric field between the plates increase, decrease or stay the same? Explain. How can this field be measured?
