6)Two point charges, Q1 = -5.8 μC and Q2 = 2.2 μC , are located between two oppositely charged parallel plates, as shown in the figure. (Figure 1) The two charges are separated by a distance of x = 0.32 m . Assume that the electric field produced by the charged plates is uniform and equal to E = 73000 N/C . A) Calculate the net electrostatic force on Q1. Express your answer to two significant figures and include the appropriate units

The figure below shows a small, charged sphere, with a charge of q = +41.0 nC, that moves a distance of d = 0.162 m from point A to point B in the presence of a uniform electric field E of magnitude 290 N/C, pointing right. 9 A E d (a) What is the magnitude (in N) and direction of the electric force on the sphere? N magnitude direction = B + --Select--- (b) What is the work (in J) done on the sphere by the electric force as it moves from A to B?

a. Two charges are separated by a distance of 5.0 cm. q1 has a charge of 4.0x10^-6 C and q2 has a charge of 2.8x10^-7 C. Locate the point(s) where a positive test charge could be placed to keep it in equilibrium.b. Sketch the electric field lines for this system of charges (*The screenshot diagram*).

In the picture below, the rod is positively charged. Electrically speaking, water is a "polar molecule"; each water molecule can be imagined as a negative charge (the oxygen end) and a positive charge (the hydrogen end), each of approximate magnitude 2e, separated by an approximate distance of 2 x10-1" m. a) Explain how a charged rod can exert an electric force on water molecules that have zero net charge. Include a picture of a typical water molecule in the stream of water adjacent to the rod, showing its orientation relative to the rod. b) If the charge of the rod is +32 nC and that charge is located approximately 2.0 cm from a water molecule in the stream, what is the maximum possible net electric force that the rod could exert on the molecule?

Charges on raindrops vary widely in both magnitude and sign. Consider a case where the two drops on the x-axis are 2.18 mm apart and have charge q = 769 nC, while the third drop is 10.3 mm up the x-axis and has charge Q = -2.02 μC.
