A charged particle travels undeflected through perpendicular electric and magnetic fields whose magnitudes are 4000 N/C and 20 mT,respectively.
Find the speed of the particle if it is a proton.
v= m/s
Find the speed of the particle if it is an alpha particle. (An alpha particle is a helium nucleus-a positive ion with a double positive charge of +2e.)
v= m/s
