URGENT!!(adsbygoogle = window.adsbygoogle || []).push({});

Hi, I have a couple of urgent problems which are listed below. I am not sure what to do in either of them! If someone could help me as soon as possible that would be great!

Cheers

Problems:

1. Consider a linearly polarised plane wave incident normally on a slab of material that absorbs it completely. Use the Maxwell stress tensor to show that the pressure exerted on th screen is = to the energy density of the incoming field. Check that this agrees with the simpler method of using the momentum density of the field

2. Two charges of q at a distance r repel each other according to Coulomb's Law. Choose a suitable surface sorrounding one of the charges and calculate F by integration of the Mawell stress tensor
