`v_"Cathode" = E / B `

Enter a value for all fields

The Speed of a Cathode Ray equation computes the speed of a cathode ray using:

• `E` = Electric field
• `B` = Magnetic field

Velocity(v): The equation returns velocity(v) in m/s. However, this can be automatically converted to other velocity units via the pull-down menu.
