Uniformly charged field

According to this book, the electric field outside a uniformly charged,infinite cylindrical conductor is the same as if the cylinder's charge were concentrated in a thin wire along the cylinder's axis. Moreover, the potential inside a uniformly charged infinite cylindrical pipe, like that inside a spherical shell, is a constant. These statements are approximately true for finite cylinders and pipes as long as their lenght is much larger than their radius. Use these facts to calculate the capacitance of the coaxial cable arrangement below: C= L/2kln (R0/R2)= 2π€ L/ln (R0/R2) If L>>>R2 (a cylindrical wire inside a very long cyli... click for more

Electric field between 2 parallel plates

Imagine to circular flat plates of radius R that are separated by a small distance s. Imagine that we connect the plates to a power supply that puts opposite charges on the plates of whatever magnitude Q is necessary to set up a fixed potential difference (delta*sigma) between them. A) argue that the magnitude of the total force that each plate exerts on the other is given by F=2(pi)kQ^2/A where A is the area of each plate. What assumptions do you have to make? B) show that you can eliminate the unknown charge Q from this expression to get F=(1/8k)(R*delta*sigma/s)^2

capacitance

What will happen in the capacitor circuit below? Include in your explanation what happens to the charge distribution on the capacitors as well as what happens to the brightness of the bulb. Remember that the capacitors are filled with insulator so charge cannot cross them.

Parallel Plates

According to section E3.4, the electric field E between two parallel plates with opposite, uniformly distributed charges is ( as long as the plates are very large compared to their seperation d) nearly uniform and has magnitude E= 4(pi)k(sigma), where sigma is the charge per unit area on the plates. Use this result to verify the equation included as an attachment.

Physics

Imagine that we give N2(+), O2(+) and (NO)+ ions the same velocity of 30.0 km/s and then send them into a mass spectrometer where the magnetic field strength is B=8.5MN/C. How far would the spot on the photographic plate be from the entry point for each ion, assuming that each ion completes one-half of an orbit. The atomic mass of a nitrogren atom is 14.0031 amu and oxygen is 15.9949 amu, where 1 amu = 1.6605 x 10^-27 kg
