Question

Two small nonconducting spheres have a total charge of 92.5 µC. (a) When placed 1.08 mapart, the force each exerts on the other is 12.0 N and isrepulsive. What is the charge on each? (Round your answers to thenearest 0.1 µC.)
smaller µC larger µC

(b) What if the force were attractive?

(b) What if the force were attractive?
smaller µC larger µC smaller µC larger µC smaller µC larger µC smaller µC larger µC

Explanation / Answer

(a) let the charges of each sphere are x & y x+y=92.5 C k*x*y/(1.082)=12 xy= 1552.2 (C)2 (a) if x>0,y>0 => (92.5 -y)*y=1552.2 => y=71 C --> large one x=22 C -->small one (b)if x<0; y>0 => actrative xy= -1552.2 (C)2 =>  (92.5 -y)*y= -1552.2 => y=107 C=11*101 C x=-15C
