Question

Cathode rays are made up of electrons and cathode rays deflect when enter the magnetic field.So if we fill a room with magnets and hence get a magnetic field and then if we tie an electron with a thread and start oscillating it so will the electron oscillate or deflect due to magnetic field?

Answer 1

An electron is so small that it cannot be seen by any device.So. it is not possible to tie it with a thread.Moreover, the deflection of cathode rays was observed by the florescence produced on ZnS screen in an apparatus specially designed.
