Imagine a space station module shaped like a cylinder 30m long and 5m in diameter orbiting close to the earth above the earth's equater. What would be the maximum potential difference that could develop between the ends of the module. (I know that potential difference=EL but how do I find E? It is also equal to VB/C or v*magnetic field/speed of light).
You can find it by putting value of B (earth's magnetic field strength and velocity of module. There will be maximum ...
