The figure (Figure 1) shows some of the electric field lines due to three point charges arranged along the vertical axis. All three charges have the same magnitude. At what point(s) is the magnitude of the electric field the smallest? Explain your reasoning. Explain how the fields produced by each individual point charge combine to give a small net field at this point or points.

Four charges are distributed around a circle as shown in the figure. The point P is at the center of the circle. The magnitude of the electric field generated by each charge point P is 300 N/C. What is the (a) direction and (b) magnitude of the net electric field at point P? li Q₂ Write your answer the following way: (a) Direction (b) Magnitude (Choose from left/right/up/down); Explanation.......... N/C; Calculation / Explanation:...------

A neutral metal block is located near two balls which have equal positive charges, as shown in the diagram. Use the directional rosette to answer parts b, c, and d. в х ХА 9 zero magnitude metal block (a) Draw the approximate charge distribution on the metal block due to the two positive charges. (b) What is the direction of the net electric field at location B? Enter your number here: (c) What is the direction of the net electric field at location A? Enter your number here: (d) What is the direction of the electric field at location A solely due to the polarized charges on the block? Enter your number here:

The diagram in the attatched image shows three charges (q1, q2, q3) from left to right arranged along a straight line at the distances given. The charge at q1 is -11 μC, q2 is 7 μC, and q3 is -3 μC. a. Calculate the magnitude and direction of the net electric field E at the location of q2 b. Assuming that charges q1 and q3 are fixed (immobile), but q2 (mass = 1.5 μg) is free to move, calculate the magnitude and direction of the acceleration of q2.
