Two plates of area 30.0 cm^2 are separated by a distance of 0.0590 cm. if a charge separation of 0.0240 μc is placed on the two plates, calculate the potential difference (voltage) between the two plates. assume that the separation distance is small in comparison to the diameter of the plates.

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
