Question

need help with these problems

Gauss's law is always true. It is not always helpful for solving problems. Explain what elements of a problem make Gauss' law a useful approach. Gauss's law is based on the idea that the flux through this imaginary surface should be proportional to the amount of field source inside the surface. Based on that assumption, would it stand to reason that any force for which that assumption is true would have an inverse square law dependence? Would you expect to be able to write a meaningful version of Gauss' law for Newton's law of universal gravitation? If we have a solid, uncharged conductor with a cavity cut in it, and we place a charge in that cavity, we know two tilings: 1. The electric field inside the conductor is zero and 2. The electric field outside the conductor is not zero, that is the charge placed inside the cavity produces a field outside the conductor. Explain how this can happen.

Explanation / Answer

1. you have to be do the integral E*dA

so is E is the samea cross the surface the integral can be done easily

2. yes it can

net gravity = menclosed/(4 pi G)

3.

charges will accumulate on the innter surface to make qenc for inside the conducotr zero

but since charge will have to balance other charge will accumulate on the outer surface
