Question: Suppose you have a fixed charge of -15.0 nC at point X. Points A and B are to the right of point X at distances of 20.0 cm and 40.0 cm from X respectively.
Calculate the following:
a) the potential at points A and B
b) the potential difference between A and B
c) the potential energy of a proton at A and B
d) the speed at point B of a proton that was moving to the right at point A with a speed of 4.0 x 10^5 m/s
e) the speed at point A of a proton that was moving to the left of point B with a speed of 1.0 x 10^5 m/s
Three positive charges, A, B, and C, of 3 · 10-6, 2 · 10-6, and 2 · 10-6 coulombs, respectively, are located at the corners of an equilateral triangle of side 0.2 m - Find the magnitude in newtons of the force on each charge.
