Homework Statement Each of the protons in a particle beam has a kinetic energy of 3.25 x 10^-15 J. What are the magnitude and direction of the electric field that will stop these protons in a distance of 1.25 m? Homework Equations Felectric = kC (q*q/r^2) Electric Field= Felectric/q...

Wow thanks! haha I may have some more questions soon too :)

Force of gravity = mass x 9.8

F= mg

(Electric field equals the electric force divided by the charge of the object)

Electric field = Electric force/ q (charge of object)

Homework Statement An object with a net charge of 24 x 10^-6 Coulombs is placed in a uniform electric field of 610 N/C, directed vertically. What is the mass of this object if it floats in this electric field? Homework Equations Felectric = kC (q*q/r^2) Electric Field= kC (q/r^2) E=...
