Return to Blackboard Cutnell, Physics, 10e Chapter 18, Problem 05 Consider three identical metal spheres, A. B, and C. Sphere A carries a charge of Bo. Sohere B carrles a charge of q. Sphere C carries no net charge then touched to sphere A and separated from it. Lastly, sphere C is touched to sphere B and separated from it (a) what is the ratio of the spheres to a (b) before they are allowed to touch each other and (c) after they have touched?

Explanation / Answer

Case 1:Initial charges of spheres

QA=+8q ,QB =-q ,QC =0

Case 2:Spheres A and B touched each other and seperated then final charge on spheres A and B is

QA =QB =(8q-q)/2 =+3.5q

Case 3:Sphere C and A touched each other and seperated then final charge on spheres A and C is

QA=QC =(3.5q+0)/2 =+1.75q

Case 4:Sphere C and B touched each other and seperated then final charge on spheres B and C is

QB=QC =(3.5q+1.75)/2 =+2.625q

a)

Therefore

QC=2.625q

QC/q =+2.625

b)

Qtotal =(8q-q+0) =+7q

Qtotal/q =+7

c)

Qtotal =(2.625+2.625+1.75)q=+7q

Qtoal/q =+7
