1 .- Three charged particles are in a straight line and separated by a distance d, as shown in Figure 25-19. Remain fixed q1 and q2. Q3 load, which can move freely in equilibrium under the action of electric forces. Get a function of q2 q1.
SOLUTION:
2 .- A straight rod of length L is lineated with the x axis and its ends are at x = - L / 2 and L / 2 ( Figure 22.15). The total load of the rod is zero, but the charge density is not, is given by λ (x) = 2λ0x / L Calculate the force exerted on a charge q located at a point x = R on the x-axis to the extreme right
Solution:
3 .- Determine the electric field in the center of the square in Figure 26-26. Suppose q = 11.8 nC and a = 5.20 cm Solution:
