There are two telescopes observing at night. The first telescope is 0.3m and has a focal ratio of f/8. The second telescope has a focal ratio of f/4 and is 30m in diameter. They each have an identical CCD camera whose pixels are 25 microns on a side.
A -3.4 nC charge is on the x-axis at x1 = -7 cm and a 4.2 nC charge is on the x-axis at x2 = 13cm.At what point or points on the y-axis is the electric potential zero?Express your answer using two significant figures.
Two stationary positive point charges, charge 1 of magnitude 3.80nC and charge 2 of magnitude 1.70nC , are separated by a distance of 59.0cm . An electron is released from rest at the point midway between the two charges, and it moves along the line
