An electron and a proton are each placed at rest in a uniform electric field of magnitude 554 n/c. calculate the speed of each particle 52.0 ns after being released. electron m/s proton m/s need ?

The best description is: . nobody has any idea what q is.

Hellosubatomic particles  are  particles  that are smaller than the atom. protons, neutrons, and electrons are the three mainsubatomic particles  found in an atom. protons have a positive (+)  charge. an easy way to remember this is to remember that both neutron and no  electrical charge  start with the letter "n."have a nice day
