Two situations are shown below. In situation (1), a
negative charge (A) is placed near a single positive charge. In
situation (2), the same negative charge (A) is placed the same
distance away the positive end of a dipole.
Please explain your answer.

Please explain and write clearly:
Two charges are placed near a large, flat, conducting plane such that the line joining the charges strikes the conductor at a right angle. The closer charge is exactly halfway between the conductor and the more distant charge. The charge density at the point on the conductor in line with the two charges is measured to be exactly zero. a. Compute the ratio of the two charges qlz, including the sign (negative if they 4...

To do so, we shall start with empty space and then add into that space one charge at a time until we have completely assembled the triangle of three charges. The legs of the right triangle have dimensions dx = 6.16e-02 meters and dy = 1.1e-02 meters. de 92 93 dy 91 The charges are as follows: • 91 =...

Consider two charges, one positive charge +0 and one negative charge -0, as shown in the figure below. The charges lie at two corners of a square of side L. Draw the electric field vectors at point O (at the center of the square) and at point P at the empty fourth comer of the square). Calculate the net electric fields at both point O and at point P. Please give your a) b) answers in component form. (Note: You...

Points: 1 13) Is it possible to have a zero electric potential between two positive charges along the line joining the two charges? A) Yes, if the two charges are equal in magnitude. B) No, a zero electric potential cannot exist between the two charges. C) Yes, regardless of the magnitude of the two charges. D) cannot be determined without knowing the separation between the two charges E) cannot be determined without knowing the magnitude of the charges Points: 3...

Question 5 [20 marks) Consider Coutte flow, which occurs when we have a fluid suspended between two parallel plates, one of which is moving and the other of which is stationary. The velocity profile between these two plates is linear. We have water between these two plates and distance separating them of 1 mm. Given this information: (a) What is the force exerted on the stationary plate per m2 if the moving plate has a velocity of 0.1 m/s in...

You have two charges +4q and one charge -q. (a) How would you place them along a line so there's no net force on any of the three? Options: One positive charge must be at the midpoint between the other two charges. The negative charge must be at the midpoint between the two positive charges. One positive charge must be four times the distance from the negative charge as it is from the other positive charge. There is no way...
