Chapter 18, Problem 09 Two spherical objects are separated by a distance of 1.55 x 103 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of 4.69 10-21 N. How many electrons did it take to produce the charge on one of the objects? Number Units...

Chapter 21, Problem 07 Your answer is partially correct. Try again. A magnetic field has a magnitude of 0.0013 T, and an electric field has a magnitude of 3.6 × 103 N/C. Both fields point in the same direction. A positive 2.6-4C charge moves at a speed of 4.2 x 106 m/s in a direction that is perpendicular to both fields. Determine the magnitude of the net force that acts on the charge. B Ē 9 ✓ 90° X Number...
