The attractive electrostatic force between the point charges 9.68x10-6 C has a magnitude of 0.385 N when the separation between the charges is 7.18 m. and ▾ Part A Find the sign and magnitude of the charge Q. Express your answer in coulombs.

The diagram above shows a coaxial cable. The inner conductor has radius a = 0.0025 m. The outer conductor is a cylindrical shell with inner radius b = 0.0075 m, and outer radius c = 0.008 m from the center. Both conductors are coaxial. For every length L = 10 m of cable, there is a total charge q = 2.8e-08 C on the inner conductor and a total charge of Q = -5.6e-06 C on the outer conductor. Determine the electric potential difference between the labeled points A and B.

Calculate the magnitude and direction of the Coulomb force on each of the three charges shown in the figure below. 6.00 μC charge: magnitude direction 89.855 X Your response differs from the correct answer by more than 10%. Double check your calculations. N toward the left V 1.50 μC charge: magnitude direction 29.9585 X Your response differs from the correct answer by more than 10%. Double check your calculations. N toward the right v -2.00 μC charge: magnitude direction -29.9585 X The response you submitted has the wrong sign. N toward the left V 6.00 μC + 1.50 μC -2.00 μC 3.00 cm -2.00 cm →

Red blood cells can often be charged. Consider two red blood cells with the following charges: -17.6 pc and +49.8 pC. The red blood cells are 3.31 cm apart. (1 pC = 1 × 10-12 C.) ..(a)..What.is.the magnitude of the force on each red blood cell? Enter a number. alculate the force of a charged particle on another charged particle? N Are the red blood cells attracted or repulsed by each other? attracted repulsed (b) The red blood cells come into contact with each other and then are separated by 3.31 cm. What magnitude of force does each of the red blood cells now experience? What is the net charge of the system? Assuming the cells are identical, how much charge will each have after contact? N Are the red blood cells attracted or repulsed by each other? attracted repulsed
