Sketch the topographic map you would expect as you walk away from the ocean up a gently sloping uniform beach. Label the gravitational equipotentials as to relative height and potential value. Show how to predict, from the map, which way a ball would accelerate if it was initially rolled up the beach away from the water.
Answer to relevant QuestionsA pair of parallel plates is charged by a 12-V battery. If the electric field between the plates is 1200 N/C, how far apart are the plates? Compute the energy necessary to bring together (from a very large distance) the charges in the configuration shown in Fig. 16.24. In Exercise 20, if the ground is designated as zero potential, how far above the ground is the equipotential surface corresponding to 7.0 kV? In exercise A uniform electric field of 10 kV/m points vertically upward. How far ...If it takes + 1.6 x 10-5J to move a positively charged particle between two charged parallel plates, (a) What is the charge on the particle if the plates are connected to a 6.0-V battery? (b) Was it moved from the negative ...(a) For a parallel plate capacitor with a fixed plate separation distance, a larger plate area results in (1) a larger capacitance value, (2) an unchanged capacitance value, (3) a smaller capacitance value. (b) A 2.50-nF ...
