82. The work done is equal to the change in the (total) electric potential energy U of the system, where 32 13 12 012 023 013 444 qq U rrr πε =++ and the notation r 13 indicates the distance between q 1 and q 3 (similar definitions apply to r 12 and r 23 ). (a) We consider the difference in U where initially r 12 = b and r 23 = a , and finally r 12 = a and r 23 = b ( r 13 doesn’t change). Converting the values given in the problem to SI units
