A, B and C are three indenticalmetallic spheres havingpositive, negative and positive charges, respectively.The deficiency or excess of electrons present in A, B and C are 10, 20 and 31, respectively. Initiallythe spheres A and B are brought in contact and then B and C are brought together. Determine the magnitude andnature of charge present on the bodies after bringingthem in contact. (Take charge of electorn as 1.6xx10^(-19)C ).

Answer» Solution :(i) CHARGE each conductor when they brought together `= (q_(1)+q_(2))/(2)` where `q_(1)` and `q_(2)` are the charge on each body. (ii)`A RARR -8 xx 10^(-19)C` B and C + 20.8`xx10^(-19)C`
