Charge Q1 is located at the +70.0-cm mark along an axis. Charge Q2 is located at the -20.0-cm mark along the same axis. Where along the axis must a third charge Q3 be placed in order for the net electric force upon it to be 0 N? We know that: Q₁ = -7.60 μC Q2 = +5.50 μC Express your answer as a coordinate value (+ or -) in cm. Coordinate Location of Q3___ cm

A charge q1 equal to 0.500 μC is at the origin, and a second charge q2 equal to 0.800 μC is on the x axis at 4.00 cm. Find the force (magnitude and direction) that 0.500-μC charge exerts on 0.800-μC charge. Enter a positive value if the force acts in the +x direction and a negative value if the force acts in the -x direction. (Express your answer to three significant figures.) Find the force (magnitude and direction) that 0.800-μC charge exerts on 0.500-μC charge. Enter a positive value if the force acts in the +x direction and a negative value if the force acts in the -x direction. (Express your answer to three significant figures.) How would your answers change if q2q2 were -0.800 μC? The magnitudes of the forces would rise, while the directions would be the same.   The magnitudes of the forces would rise and the directions would change to opposite.   The directions of the forces would change to opposite, while the magnitudes would be the same Answers would be the same.

Two charges lie in a line along the x axis. Charge 1 is q1 = 1.1 C and charge 2 is q2 = 2.15 C. They are each a distance of d = 0.093 m from the origin. What is the distance on the x-axis from the origin at which the electric field will be zero. Give your answer in meters.

Four identical charged particles (g = +10.1 µC) are located on the corners of a rectangle as shown in the figure below. The dimensions of the rectangle are L = 64.2 cm and W = 14.6 cm. L (a) Calculate the magnitude of the total electric force exerted on the charge at the lower left corner by the other three charges. (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)
