The drawing shows two situations in which charges are placed on the x and y axes. They are all located at the same distance of 5.00 cm from the origin O. For each of the situations in the drawing, determine the magnitude of the net electric field at the origin. -l.0 μC +1.0 uC +2.0 uC -3.0 µC +4.0 µC -1.0 uC o! +6.0 uC (b) (a)

In the figure eight particles form a square in which distance d = 2.80 cm. The charges are q1 = +7e, q2 = +4e, q3 = -5e, q4 = -6e, q5 = +7e, q6 = +4e, q7 = -5e, and q8 = +3e. What is (a) the x component and (b) the y component of the net electric field at the square's center?

A hydrogen atom is made up of a proton of charge +Q = -1.60 x 10-19 C and an electron of charge -Q = -1.60 x 10-19 C. The proton may be regarded as a point charge at r = 0, the center of the atom. The motion of the electron causes its charge to be "smeared out" into a spherical distribution around the proton (Figure 1), so that the electron is equivalent to a charge per unit volume of p(r) = -(Q/Tao)e 2r/a0, where ao = 5.29 x 10-11 m is called the Bohr radius. (a) Find the total EXECUTE Part C Integrate the expression and solve the linear system from previous part to find the total charge Q(r)encl within radius r. amount of the hydrogen atom's charge that is enclosed within a sphere with radius r centered on the proton. (b) Find the electric field (magnitude and direction) caused by the charge of the hydrogen atom as a function of r.c) Make a graph as a function of r of the ratio of the electric-field magnitude E to the magnitude of the field due to the proton alone.

A charged 3.60 g glass bead hangs suspended in the air by an electric field. If the bead was charged by the removal of 7.10×1010 electrons, what must the electric field magnitude be?  2.56×1011 N/C 3.11×106 N/C 4.97×10-13 N/C 3.17×108 N/C

A small glass bead charged to 7.0 nC is in the plane that bisects a thin, uniformly charged, 10-cm-long glass rod and is 4.0 cm from the rod's center. The bead is repelled from the rod with a force of 940 μN. What is the total charge on the rod? Express your answer with the appropriate units
