A parallel-plate capacitor consists of two plates, each with an area of 25  cm2 separated by 3.0  mm . The charge on the capacitor is 4.8  nC . A proton is released from rest next to the positive plate. How long does it take for the proton to reach the negative plate? Express your answer with the appropriate units.

A plastic disk of radius R = 72.2 cm is charged on one side with a uniform surface charge density 7.67 fC/m², and then three quadrants of the disk are removed. The remaining quadrant is shown in the figure. With V = 0 at infinity, what is the potential in volts due to the remaining quadrant at point P, which is on the central axis of the original disk at distance D = 0.429 cm from the original center? D

A charge Q = 2.00 10-8 C is surrounded by an equipotential surface with a surface area of 1.23 m2. What is the electric potential at this surface? V

A thin, spherical, conducting shell of radius R is mounted on an isolating support and charged to a potential of -667 V. An electron is then fired directly toward the center of the shell, from point P at distance r from the center of the shell (r>>R). What initial speed vo is needed for the electron to just reach the shell before reversing direction? Number i Units
