## Main Question or Discussion Point

Say you have a cathode ray gun and it is connected to a 10kV power supply, which is also connected to negatively charged parallel plates. Can you calculate the speed of the electron(s) which go from the heated coil to the plates, and only information given is voltage of power supply, charge of electron (ㅣQㅣ= 1.6 x 10^(-19) C ) and the mass, which is 9.1 x 10^(-31) kg.

If so, how?

If not, what more information is required to be able to solve this problem?

Thanks!
