Concept explainers
You have a small metal sphere fixed on an insulating stand and another sphere attached to a plastic handle. You charge one of the spheres and then touch it with the second sphere. Draw a force-versus-time graph for the force that one sphere exerts on the other as you move the sphere on the handle slowly and steadily away from the sphere on the stand. What information do you need in order to determine the magnitudes of the quantities on the graph?

Charged plates establish an electric field on a region of gel between the plates. A solution of DNA fragments, which acquire a negative charge in solution, is analyzed by using an electric field to drive the fragments through the gel. A drag force opposes the motion, causing the fragments to move at a constant speed. Larger fragments move more slowly, so the fragments separate by size to give a “fingerprint” of the sample. The fragments move in the direction of _________ electric potential and __________ electric potential energy.A. higher, higherB. higher, lowerC. lower, higherD. lower, lowerarrow_forward

Suppose it moves within the vicinity of an extremely heavy (fixed in place) particle with a positive charge Q and mass M. When the light particle is xi distance from the heavy particle, it is moving directly away from the heavy particle with a speed of vi. a) What is the lighter particle's speed when it is xf away from the heavy particle? (Consider the Newtonian Gravitation acting between the two charged particles. Ignore the effects of external forces) Solution: We may solve this using two approaches. One involves the Newton's Laws and the other involving Work-Energy theorem. To avoid the complexity of vector solution, we will instead employ the Work-Energy theorem, more specifically, the Conservation of Energy Principle. Let us first name the lighter particle as object 1 and the heavy particle as object 2. Through work-energy theorem, we will take into account all of the energy of the…arrow_forward
