The discussion centers on calculating the charge of a sphere with a diameter of 0.26 meters that produces an electric field of 1030 N/C at its surface. Participants emphasize the application of Gauss's Law, which states that the electric field E is related to the charge q by the formula E = (1/(4π(ε₀))(q/r²), where ε₀ is the permittivity of free space (approximately 8.85 x 10^-12 F/m). To find the charge q, the rearranged formula q = E * (4π(ε₀) * r²) should be used, where r is the radius of the sphere.
PREREQUISITESStudents of physics, electrical engineers, and anyone interested in understanding electrostatics and charge calculations using Gauss's Law.
The idea is for you to use Gauss's law to find the formula that you need. That's what @Chandra Prayaga indicated in post #2.elleo said:Is this formula:
E=((1)/(4(3.1416)(8.85X10^-12)) ((q)/(r)^2)
But what is the formula to calculate the q, the charge given the E (electric field) and r (distance)
