The number of electrons delivered at the cathode during electrolysis by a current of 1A in 60 seconds is (charge of electron =1.6 times 10^(-19) C )

A flow of 10^(7) electrons per second in a conduction wire constitutes a current of

Determine the number of electrons flowing per second through a conductor, when a current of 32A flows through it.

Assertion: The drift speed of electrons in metals is of the order of few mm / s and charge of an electron is very small (1.6 xx 10^(-19) C) . Yet a large amount of current is obtained. Reason: At room temperature, the thermal speed of electron is very high ( 10^7 times the drift speed). Which one of the following statements is correct?

In the Bohr model of hydrogen atom, the electron is treated as a particle going in a circle with the centre at the proton. The proton itself is assumed to be fixed in an inertial frame. The centripetal force is provided by the Coloumb attraction. In the ground state, the electron goes round the proton in a circle of radius 5.3xx10^-11m . Find the speed of the electron in the ground state. Mass of the electron =9.1xx10^-31 kg and charge of the electron = 1.6xx10^-19C .
