There are two identical, positively charged conducting spheres fixed in space. The spheres are 31.4 cm apart (center to center) and repel each other with an electrostatic force of F = 0.0735 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 F, = 0.115 N. The Coulomb force constant is k = 1/(4re0) = 8.99 × 10°N• m²/C². Using this information, find the initial charge on each sphere, q1 and q2, if q1 is initially less than q2. q1 = 92 = C

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
