A line of charge lies along the x-axis extending from x=0m to x=3m. The line charge densit is a function of the distance from the coordinate beginning x and is given by λ=2x [nC/m].
a) Find the total charge of the line charge Q.
b) Using Coulombs law calculate the electric field on the x-axis at x=6m and at x=250m.
c) Find the field at x=250, assuming that you have a point charge at x=0 whose charge is the same as the total charge Q of the line charge.
d) Compare the result with the value calculated under b. Comment on the difference between the two values.
Given that 12g of carbon combines with 16g of oxygen to form carbon monixide, how various grams of carbon monoxide can be made from 48g of carbon and 48g oxygen.
The spin dynamics in most spin-ice materials is very classical and has little quantum fluctuations. So the question is that which spin-ice materials have strong quantum fluctuations? What are the model Hamiltonian for the spins in those materials?..
