Finding the speed of a proton in a mass spectrometer

[Mack199]

Homework Statement

A mass spectrometer uses either a magnetic field or an electric field to deflect charged particles.

A proton starts from rest a plate P. The Speed of the proton as it passes through the hole in plate Q is?

V= 10000 V
Mass of a proton = 1.67x10^-27
Charge of a proton = 1.6x10^-19

With this you then need to find the magnetic field intensity.

Radius of curvature of a protons path is 3.00 m.

Homework Equations

I have no clue?

Hi Mack, welcome to PF.
To get help, you need to show what you know about the topics and how you tried to solve the problem.

Read about the working principle of mass spectrometers. For example, http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/maspec.html
