A+4.0- mc charge is placed on the x axis at x = +3.0 m, and a -2.0- mc charge is located on the y axis at y = -1.0 m. point a is on the y axis at y = +4.0 m. determine the electric potential at point a (relative to zero at the origin).

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

not too sure thinking all accelerations are pointed down
