The discussion focuses on calculating the area of metal plates given a charge of 3,000 coulombs and a separation distance of 0.5 mm. The formula used is C = Epsilon0(A) / delta x, where Epsilon0 is 8.85 × 10^-12. The user initially calculated an incorrect area of 1.6 × 10^11 meters, while the expected answer is approximately 250 miles, which translates to around 402,336 meters. The discussion emphasizes the importance of providing complete problem details for accurate assistance.
PREREQUISITESStudents and professionals in physics or electrical engineering, particularly those working with capacitors and electric fields, will benefit from this discussion.
MarkFL said:Can you state the entire problem as given?
Mango12 said:Now let's find the area of the metal plates. We already know from a previous problem that there is a 3,000 coulomb charge on the plates. The plates are placed .5mm apart. (approximate answer is 250 miles, but give your answer in meters)
MarkFL said:If a problem depends on a previous problem, then you need to give all relevant information, all in one place, so people don't have to guess at what's going on or chase the information down in other threads. (Whew)
