A particle has a charge of 5 nC and is located at the origin of an x-y grid. What is the magnitude of the electric field due to this particle at the location in space given by the coordinates (x

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
