Two conducting spheres of Radius R1 and R2 each have an initial charges of Qi1 and Qi2 respectively. The two spheres are brought together until they make contact. After they are in contact find the ratio of the charge density of sphere 1 to sphere 2. In other words, find Charge density f1/ Charge density f2

There are two identical, positively charged conducting spheres fixed in space. The spheres are 32.0 cm apart (center to center) and repel each other with an electrostatic force of F1 = 0.0750 N. Then, 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 F2 = 0.100 N. Using this information, find the initial charge on each sphere, q1 and q2 if initially...

There are two identical, positively charged conducting spheres fixed in space. The spheres are 47.8 cm apart (center to center) and repel each other with an electrostatic force of F1 = 0.0720 N. Then, 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 F2 = 0.115 N. Using this information, find the initial charge on each sphere, q1 and q2 if initially...
