There is a 30 microcoulomb charge at the origin.  There is a 154 microcoulomb charge on the x axis at x = 4 meters, and a 146 microcoulomb charge on the y axis at y = 4 meters.  What is the magnitude of the net force from the interaction between the charges on the 30 microcoulomb charge at the origin.  Give you answer in Newtons

Two charges, Q A -4.0 µC and QB +4.0 µC are placed at locations A = (-4.0,+4.0) cm and B = (2.0, –4.0) cm, respectively. A third charge q = +1.0 µC is placed at the origin. y QA -> + QB a) Sketch a figure illustrating this situation. Draw vectors of the electric forces exerted on charge q by the other two charges. Clearly label each vector. b) Calculate magnitudes of the electric forces exerted by each of these charges on charge q. c) Determine the magnitude of the net electric force on charge q. d) Determine the direction of the net electric force on charge q. Provide your answer in degrees, as an angle measured counterclockwise from the +x axis. ४

The figure below shows three small, charged beads, all lying along the horizontal axis. Bead A, at left, has a 6.65 nC charge. Bead B has a 1.10 nC charge and is 3.00 cm to the right of A. Bead C has a -2.05 nC charge and is 2.00 cm to the right of B. 3.00 cm qB direction -2.00 cm 9c (a) What is the magnitude (in N/C) of the electric field at a point 2.00 cm to the right of A? 18625 X Draw the directions of the electric field vectors, due to each of the three charges, at the point to the right of A. What are the signs of the charges? How does this affect the directions of the field vectors? What is the magnitude of the electric field due to a point charge? Add the fields as vectors to get the net field. Be careful with units and signs. N/C (b) A fourth bead with a charge of -8.00 nC is placed at this point. What are the magnitude (in N) and direction of the net electric force on it? magnitude 14.9 X From part (a), what is the electric field at the given point? If we place a charged…

Two pollen grains each possess a net electric charge. The left grain has g₁ = 7.4×10-6 Coulombs of charge, and the right grain has q₂ = 3.5×106 Coulombs of charge. The pollen grains are separated in space by a distance of r = 0.14 meters. How strongly do the pollen grains electrically push or pull on each other (in Newtons)? Recall that the Coulomb constant is k = 8.99 × 109 N. m² x
