Asked by Rosh
what electric field strength would be required to suspend an alpha particle? (contains 2 protons and 2 neutrons) The answer should be 2.05 x 10^-7 N/C.
I am not given distance so I am not sure how I should solve this particle problem.

gravity pulls down , the electric field pushes up
find the weight and charge of the α-particle
the field strength is Newtons per Coulomb
... the electric force equals the gravitational force
charge * field strength = m * g
