Bead A has a mass of 14 g and a charge of -4.6 nC . Bead B has a mass of 22 g and a charge of -14.0 nC . The beads are held 15 cm apart (measured between their centers) and released. What maximum speed is achieved by each bead? Express your answers using two significant figures separated by a comma. vfA, vfB =
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?
A +10.00 nC point charge with a mass of 4.00 g is placed 45.0 cm from the surface of a solid conducting sphere having a radius of 115 cm and a net charge of +2.00 μC.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...
