Understanding:
1) Charge flown through the cross section of wire is given by Q = I t,
where I is current through that wire and t is time interval.
Let n be no. of electrons.
Total Charge flown, Q = 0.1 * 60s
=> n e = 6C
=> n * 1.6 * 10^(-19) = 6C
=> n = 6/1.6 * 10^(19)
=> n = 0.267 * 10^19
=> n = 2.67*10^(18)
Therefore, number of electrons passed through cross section of wire is 2.67 * 10^(18) .
