A nervous physicist worries that the two metal shelves of his wood frame bookcase might obtain a high voltage if charged by static electricity, perhaps produced by friction. What is the capacitance of the empty shelves if they have area 0.375 m² and are 0.245 m apart? capacitance of shelves: What is the voltage between the two shelves if opposite charges of magnitude 2.75 × 10-⁹ C are placed on them? voltage between shelves: energy stored: 1.35 x10-11 Calculate the energy stored by having this charge on the two shelves. 203.70 Incorrect 407.41 Incorrect F V J
