Question

How did the value of \[e/m\] depend on the gas introduced in the discharge tube?

Options

• It depended on the gas introduced in the discharge tube.

• It was determined by the colour of the gas.

• It was independent of the gas introduced in the discharge tube.

• It was measurable only when no gas was introduced.

Answer 1

The value of \[e/m\] did not change with the gas introduced in the discharge tube. This was another observation supporting universality.
