Three point charges are located at the vertices of an equilateral triangle. The charge at the top vertex of the triangle is given in the figure. The two charges q at the bottom vertices of the triangle are equal. A fourth charge 5 µC is placed below the triangle on its symmetry- axis, and experiences a zero net force from the other three charges, as shown in the figure below. –3.9 μC 9 -1.9 m 5.1 m 5 μC Find q. The value of the Coulomb constant is 8.98755 x 10º N - m²/C².

Please answer both.

Six electric field lines are drawn coming from a positive charge of 3 nC. Many of these lines end on a nearby second charged object, but two of the lines escape out to infinity. What charge must that second object carry?

Four charges are at four corners of a square of side d. A positive fifth charge is at the center of the square as shown in the figure below. Which of the arrows represent the direction of the net force acting on the charge at the center of the square? +2Q d. +2Q C +Q -Q +2Q B.

You have two identical conducting spheres, each of mass m, the first one being charged twice as the second one, and the spheres are charged with oppositely charges. They are separated by a distance 'd. What should be the charge on the spheres so the force of attraction between the spheres will be equal to the weight of each sphere ? Take Coulomb constant as simply 'k'. q1 = (d/2)(mg/k), q2 = (d/2/2)(mg/2k) 91 = (d/2)(mg/2k), q2 = (d/ 2)(mg/k) 91 = (d//2)(mg/k), q2 = (d/2/2)(mg/k) %3D O 41 = (2d//2)(m²g/k), q2 = (d/2/2)(mg/2k)

The figure below shows four small beads, each with a positive charge, at the corners of a square. The length of each side of the square is a. The bead at top-right has a charge of q; the one at lower-left has a charge of 8.0q; the other two each have a charge of 6.0g.
