|Feb4-13, 10:58 AM||#1| 1. The problem statement, all variables
and given/known data You have two identical tiny conducting
spheres: sphere A carries positive charge qA, and sphere B
carries negative charge qB. First the spheres are placed
distance d = 0.404 m apart, and they attract each other with a
force F1 = 0.748 N. Then the spheres are brought together, touch
each other, and are brought back to distance 0.404 m apart. Now
the spheres are both positive, and they repel each other with
force F2 = 0.59 N. Find the original charge on each sphere. 2.
Relevant equations 3. The attempt at a solution after the
spheres touch i get qf=(q1+q2)/2 and i solve for the charge on
the spheres after they touch and get .1035uC as my answer but im
not sure how to find original charge after that my proffesor
never did an example like this any help is welcome and
appreciated |Feb4-13, 11:41 AM||#2| Charge is conserved. Make
use of that along with F1. Besides, this belongs in the
introductory physics section. |Similar discussi
