A 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?
Answer to relevant QuestionsHow much work is required to completely separate two charges (each -1.4μC) and leave them at rest if they were initially 8.0 mm apart? Compute the energy necessary to bring together (from a very large distance) the charges in the configuration shown in Fig. 16.25. Determine the potential 2.5 mm from the negative plate of a pair of parallel plates separated by 20.0 mm and connected to a 24-V battery. Calculate the voltage required to accelerate a beam of protons initially at rest, and calculate their speed if they have a kinetic energy of (a) 3.5 eV, (b) 4.1 keV, and (c) 8.0 x 10-16 J. A 12.0-V battery remains connected to a parallel plate capacitor with a plate area of 0.224 m2 and a plate separation of 5.24 mm. (a) What is the charge on the capacitor? (b) How much energy is stored in the capacitor? ...
