The electric field just outside the surface of a hollow conducting sphere of radius 20 cm has a magnitude of 500 n/c and is directed outward. an unknown charge q is introduced into the center of the sphere and it is noted that the electric field is still directed outward but has decreased to 100 n/c. what is the charge q?

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
