Two small insulating spheres with radius 6.00×10−2 mm are separated by a large center-to-center distance of 0.460 mm . One sphere is negatively charged, with net charge -1.00 μCμC , and the other sphere is positively charged, with net charge 3.30 μCμC . The charge is uniformly distributed within the volume of each sphere.

a) What is the magnitude EE of the electric field midway between the spheres?

Take the permittivity of free space to be ϵ0ϵ0= 8.85×10−12 C2/(N⋅m2)C2/(N⋅m2) .

There are two identical, positively charged conducting spheres fixed in space. The spheres are 34.8 cm apart (center to center) and repel each other with an electrostatic force of ?1=0.0675 N . A thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed, the spheres still repel, but with a force of ?2=0.115 N . The Coulomb force constant is ?=1/(4??0)=8.99×109 N⋅m2/C2 . Using this information, find the initial charge on each sphere,...

Two small spheres, A and B, are separated by a distance of 1.5 m as shown below. Sphere A has a charge of 3 μC and Sphere B has a charge of -6 μC. (The prefix \"μ\" means \"micro\" which is a \"millionth.\" So, 1 microCoulomb = one-millionth of a Coulomb = 10-6 C.) Sphere C, is now moved to a new position that is directly above Sphere A. The distance between A and C is still half the distance...
