Question
(a) Two of the spheres are brought together so they touch, andthen they are separated. Which spheres are they, if the finalcharge on each one is +5.0 C? (b) In a similar manner, which three spheres are brought togetherand then separated, if the final charge on each of the three is+3.0 C? (c) The final charge on each of the three separated spheres inpart (b) is +3.0 C. How many electrons would have to be addedto one of these spheres to make it electrically neutral? 6. Four identical metalspheres have charges of , and qD = +12.0 C. (a) Two of the spheres are brought together so they touch, andthen they are separated. Which spheres are they, if the finalcharge on each one is +5.0 C? (b) In a similar manner, which three spheres are brought togetherand then separated, if the final charge on each of the three is+3.0 C? (c) The final charge on each of the three separated spheres inpart (b) is +3.0 C. How many electrons would have to be addedto one of these spheres to make it electrically neutral?Explanation / Answer
a) q + q' = 2*5.0 C = 10.0 C answer: qB and qD b) q + q' + q" = 3*3.0 C = 9.0 C answer: qA, qC and qD c) 3.0 C/1.6*10-19 C = 1.875*1013
