A +5.00 nC point charge with a mass of 4.00 g is placed 25.0 cm from the surface of a solid conducting sphere having a radius of 125 cm and a net charge of +2.00 uC.If the point charge is released, it will be repelled by the conducting sphere. Given that the point charge was initially at rest, what will be its speed when it is 75.0 cm from the surface of the sphere?

Two identical spheres each having charge Q =-11 nC and mass mOF 10 milligrams are held fixed at their positions 5.0 cm apart. A particle with charge q-+1.0 nC and mass mo-0.40 milligrams is released from rest at a position 5.0 cm from each sphere (so initially the particle and the spheres form an equilateral triangle). Find the speed of the positively charged particle when it passes a point exactly in between the two spheres. (k - 9.0 x 109...

A +3.0 nC charge Q is initially at rest a distance of 10 cm(r₁) from a +5.0 nC charge
A +3.0 nC charge Q is initially at rest a distance of 10 cm(r₁) from a +5.0 nC charge q fixed at the origin. Naturally, the Coulomb force accelerates Q away from q, eventually reaching 15 cm(r₂).The charge Q is repelled by q, thus having work done on it and losing potential energy. What is the work done by the electric field between r₁ and r₂? What is the change in the potential energy of the two-charge system from r₁...
