Homework Statement [/B] Consider two charged particles 1 and 2, each of them able to translate (move from place to place) and to spin.Homework Equations I can not completely think of relevant equations at the moment. The Attempt at a Solution [/B] I am a bit confused on how charged particles...

Homework Statement Two identical 9.60-g metal spheres (small enough to be treated as particles) are hung from separate 500-mm strings attached to the same nail in a ceiling. Surplus electrons are added to each sphere, and then the spheres are brought into contact with each other and released...

Thank you F(elec.)=.001666

I am not quite sure. The calculator scenario is F=ma. The tape and paper scenario is an electrical scenario. I am just not quite sure where the example is getting at. I know that F(mag. of E.field)= q*E But I am unsure of how to put these pieces together

.98N 100g=.1kg .1kg*9.8m/s^2=.98N

100g= .1kg (.1kg)(9.8m/s^2)= .98N?

Homework Statement A piece of tape is pulled from a spool and lowered toward a 170-mg scrap of paper. Only when the tape comes within 8.0 mm is the electric force magnitude great enough to overcome the gravitational force exerted by Earth on the scrap and lift it. Determine the magnitude and...
