Question

In a hydrogen discharged tube it is observed that through a given cross-section $3.13 \times 1 0^{15}$ electrons are moving from right to left and $3.12 \times 1 0^{15}$ protons are moving from left to right. What is the electric current in the discharge tube and what is its direction?

Options:

Answer:

A

Solution:

$I = n_{e} q_{e} + n_{p} q_{E} = 1 mA$ (towardsright)
