3 (15) Three charges, 91 = 5aC, ga = 4rd, and 9--ZuC, are placed in a line (see the tigure). It is known that the distance between g and g2 is d12 2 cm, while the distance between g2 and s is ds L.5 cm. (a) Find the force (direction and magnitude) exerted on q2 by q. (b) Find the force (direction and magnitude) exerted on ga by g. (c) Fiad the total resultant force (direction and magnitude) on g2 d12 d23 93 4. (15) charge Charge q -10 C is at a212.0cm. Find the magnitude and direction of the electric at point A on the a axis at the A 20cm

Two equal charges with magnitude Q and Q experience a force F1 when held at a distance r. F2 is the force between two charges of magnitude 2*Q and 9*Q when held at a distance r/4?

3) a)What are the magnitude and direction of the force exerted on a 4.41 pC charge by a 184 N/C electric field that points due east? magnitude direction ---Select- v b) You charge a piece of aluminum foil (mass =7.46 g) by touching it to a charged rod. The charged rod gives the aluminum foil a charge of 13 µC. Your professor brings a charged plate over and tells you to put the aluminum foil on top of the plate. To your surprise the aluminum foil hovers motionless in the air above it! Calculate the value of the electric field from the charged plate (assume it is a uniform field and the aluminum foil is a point charge). magnitude N/C direction -Select-- v
