A large point charge of q 50 microc creates an electric, Ask an Expert

Academics

A large point charge of Q = +50 microC creates an electric field and an electric potential all around it. A styrofoam bead with a mass of 35g and traveling at a speed of 10.0 m/s has a charge of q = 2.5 microC. (a) if the charged particle is 3 cm away, calculate both the potential and kinetic energies of the bead. (b) what would be the closest distance the bead would be from the point charge? (HINT for B: what would be the speed of the bead at this point? use energy conservation)
