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$?$
