Two small insulating spheres with radius 4.50×10−2 mare separated by a large center-to-center distance of 0.510 m . One sphere is negatively charged, with net charge -2.20 μC , and the other sphere is positively charged, with net charge 3.95 μC . The charge is uniformly distributed within the volume of each sphere.
What is the magnitude E of the electric field midway between the spheres?

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 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
