A uniformly charged rod of length L and uniform charge per unit length lambda lies along the x axis. Find the horizontal and vertical components of the electric field at the point P on the y axis that
is a distance d from the origin.
What are the approximate values of the E field components when d>>L?

If a balloon is taken outside on a very cold day, what will occur?

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?
