Three charges are lined up on the x-axis. Charge q1 is 5.0x10-6 C and is located at x = 6.0 m. Charge q2 is -3.5x10-6 C and is at x = -4.0 m. Charge q3 is 2.5x10-6 C and is located at x= 1.0 m. What is the total electric force that would act on a charge q3 in this situation?  Assume charge q2 is removed from the situation in the previous problem. Find the total electric field strength at the position where q2 used to be located using the same information about q1 and q3 from the previous problem

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

Honeybees acquire a charge while flying due to friction with the air. A 130 mg bee with a charge of + 23 pC experiences an electric force in the earth's electric field, which is typically 100 N/C, directed downward. What is the ratio of the electric force on the bee to the bee's weight? What electric field strength would allow the bee to hang suspended in the air?

Four identical charged particles (q = +10.7 μC) are located on the corners of a rectangle as shown in the figure below. The dimensions of the rectangle are L = 63.6 cm and W = 14.5 cm. 9 9 W L (a) Calculate the magnitude of the total electric force exerted on the charge at the lower left corner by the other three charges. N (b) Calculate the direction of the total electric force exerted on the charge at the lower left corner by the other three charges. ° (counterclockwise from the +x-axis) Need Help? Read It
