Given is a constant voltage source with U=10V to which you connect an electrical machine. Supposed you can manage that only a charge equivalent to 10 electrons is transferred from the negative electrode to the positive electrode of the voltage source and supposed there are no ohmic losses, calculate the following problem.

The electrical machine can do mechanical work. In our case it can lift up a mass of 1g. If the machine has an efficiency of 50% in transferring electrical energy to mechanical energy. What is the height up to which the mass of 1g can be lifted up?
