Explanation / Answer

Total mass of electrons M = 1.7 kg mass of single electron m = 9.11 * 10 ^ -31 kg So,No.of electrons N = M / m                                  = 0.1866 * 10 ^ 31 So, total charge of 1.7 kg of electrons   Q = Ne                                                                = ( 0.1866 * 10 ^ 31 ) ( 1.6 * 10 ^ -19 C                                                                = 0.2985 * 10 ^ 12 C (b). Total mass of protonss M = 1.7 kg mass of single proton m = 1.67* 10 ^ -27 kg So,No.of protons N = M / m                                  = 1.017* 10 ^ 27 So, total charge of 1.7 kg of protons   Q = Ne                                                                = ( 1.017*10 ^ 27 ) ( 1.6 * 10 ^ -19 C                                                                = 1.628* 10 ^ 8 C Total mass of protonss M = 1.7 kg mass of single proton m = 1.67* 10 ^ -27 kg So,No.of protons N = M / m                                  = 1.017* 10 ^ 27 So, total charge of 1.7 kg of protons   Q = Ne                                                                = ( 1.017*10 ^ 27 ) ( 1.6 * 10 ^ -19 C                                                                = 1.628* 10 ^ 8 C
