Question 2 Question 2
Shown is an apparatus for studying the properties of electrons.
Electrons from an emitter F pass through a hole in G and then move
into a region where crossed electric (L) and magnetic (M) fields are
applied. The spacing between the electric field plates at L is 1 mm.
Various target materials can be placed at W. The electrons are
detected at a phosphor coated screen labeled x-y. One scale unit
on the screen equals 1 cm.
The potential difference between F and G is 200 volts. What is the work done on electron by the electric field between F and G?
