Determine the direction of the force that will act on the charge in each of the following situations. A negative charge moving to the left in a magnetic field that points out of the screen. A negative charge moving to the left in an electric field that points out of the screen. A positive charge moving downward in a magnetic field that points upward. Answer Bank

The earth remains in orbit around the sun due to the force of gravity. how does the force of gravity exerted by the sun on the earth compare to the force of gravity exerted by the earth on the sun?

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
