Two conducting spheres are in contact with one another and each resting on insulating stands. A positively charged rod is brought near, but does not touch, the left side of the system. While holding the rod in place, the two spheres are separated and then the rod is removed. What are the resulting net charges of each sphere

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.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
