A small ball of mass m = 5.10 x 10-12 kg has acquired an - - - - - excess charge. The ball is then placed between two parallel plates spaced x = 0.00300 m apart, which have a potential difference of V = 1910 V applied across them. In this configuration, the ball appears to be motionless, or floating in between the plates. X m What is the overall charge on the ball? O positive + + + + + + + + + + + ++ + + O neutral negative Calculate the number of electrons, me, that the ball has either gained or lost. The acceleration due to gravity is g = 9.81 m/s, and the elementary unit of charge is e = 1.60 x 10-19 C. heYou cause a particle to move from point A, where the electric potential is 18.5 V, to point B, where the electric potential is '24.5 V. Calculate the change that occurs in the particle's electrostch potential energy, when the particle is an electron, a proton, a neutral hydrogen atom, and a singly ionized helium atom (i.e., lacking one electron from its neutral state). neutral hydrogen atom: J singly ionized helium atom: _ J You have a parallel-plate 5.63 x 10- F capacitor that is charged to 0.00905 C. While the capacitor is isolated, you change the plate separation so that the capacitance becomes 2.75 x 10- F. How much work W do you perform in this process? W = JA proton and an electron are fixed in space with a separation of 847 nm. Calculate the electric potential at the midpoint between the two particles. potential: Find the magnitude of the electric field at the same point. magnitude of field: N/C The direction of field is O another direction. O undetermined. O toward the proton. O toward the electron.Three point charges are arranged in a triangle as shown in he figure. D12 . Point charge @1 has a charge of 4.96 nC. + . Point charge Q2 has a charge of 5.52 nC. . Point charge Q3 has a charge of 2.05 nC. + . Point charges Q, and @2 are separated by a distance D12 of 0.126 m. . Point charges O2 and @3 are separated by a distance D23 of 0.565 m. D 23 . Point charges O, and @3 are separated by a distance D13 of 0.578 m.
