In Jellyfish fields, Patrick sees four jellyfish swimming. The first jellyfish has a charge of 58.0µC and is at the origin of a coordinate system. The second jellyfish has a charge of 31.0µC and is located 1.33m up the positive y-axis of the coordinate system. The third jellyfish has a charge of -44.0µC and is located 1.33m along the positive x-axis. The fourth jellyfish has a charge of -38.0µC and is located at the point (1.33m,1.33m) so that the four jellyfish form a square. What is the magnitude of the net force, in Newtons, on the fourth

Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of +6q. Sphere B carries a charge of -5g. Sphere C carries no net charge. Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Last, sphere C is touched to sphere B and separated from it. For the following questions, express your answers in terms of q. (a) How much charge ends up on sphere C? 0.5 (b) What is the total charge on the three spheres before they are allowed to touch each other? 0.25 (c) What is the total charge on the three spheres after they have touched? 0.375 Additional Materials M eBook JAN 12 tv MacBook Air DII 80 F7 F8 F6 esc F4 F5 F1 F2 F3 * 24 %

+1.0 uC +4.0 uC -1.0 uC +6.0 µc 13. The drawing shows four charges in which each are placed on the x and y axes. They are all located at the same distance of 5 cm from the origin O. For each of the situations in the drawing, determine the magnitude and direction of the net electric field at the origin. (show each component of the net electric field) (k = 8.99 x 10° Nm2/c2)

Two charges are placed as shown in (Figure 1) with 91 = 2.8 μC and q2 = −5.1 µC. Figure +91 0.10 m 92 0.10 m 1 of 1 A B

+3µμC +3μC Charges of 3.0 µC are located at x = 0.0, y = 2.0 m and at x = 0.0, y = -2.0 m. Unknown charges, Q, are located at x = 4.0, y = 2.0 m and at x = 4.0, y = -2.0 m. The electric field at the origin, z = 0.0, y = 0.0 m, is 4.0 x 10³ N/C î (in other words in the r direction). Determine the unknown charge Q.

Two point charges are placed on the x axis. A charge of qA= +4.54 μC is placed at x= 0 and a charge of qB= -2.87 μC is placed at x=d. When a third point charge qC is placed at x= 2.29d, the electric force on the charge at x= 0 doubles in magnitude but maintains its original direction. What is qC?

One particle has a mass of 3.71 x 10‍3 kg and a charge of +7.56 µC. A second particle has a mass of 7.17 x 103 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.177 m, the speed of the 3.71 x 103 kg-particle is 126 m/s. Find the initial separation between the particles.
