When two capacitors are joined in series the resultant capacity is 2.4 μF and when the same two are joined in parallel the resultant capacity is 10μF.their individual capacities are
Two positive charges 12μC and 10μC are initially separated by 10cm.The work done in bringing the two charges 4cm closer is
