Hello, I'm looking for some help regarding a physics problem on a Gaussian Surface.
We have a Gaussian Surface and the top part is a half of a sphere with a radius of 5m. The bottom is flat. We measure the electric field lines that uniformly exit the flat face with a value of E = 450 N/C. After that, we measure field lines that enter uniformly through the top half of the sphere normal to every point on the sphere's surface and there E = 500 N/C. Find the charge inside of the half sphere.

Hello, I'm looking for some help with a physics problem.
We have a very long conducting cylinder/wire with a radius of R0
and length of L, where R0 is much smaller than L, possesses a
uniform volume with a positive charge density pe C/m^3. Determine
the electric field at points A) outside the cylinder and inside the
cylinder. Do this for points far from the ends. Write out the steps
and details for creating the formula. b) If R0 =...
Tthe Van de Graaff generator and sphere we have been assuming since the start that they are not polarizing each other. This is an approximation. In this question we will start to be able to assess how good this approximation is ? (a) Use the approximation that the Van de Graaff generator and ball are uniformly charged spheres to find the E-field very close to the surface of the Van de Graaff generator, at the point where the +ve x-axis...
2.1 In this problem we find the electric field on the axis of a
cylindrical shell of radius R and height h when the cylinder is
uniformly charged with surface charge density . The axis of the
cylinder is set on the z-axis and the bottom of the cylinder is set
z = 0 and top z = h. We designate the point P where we measure the
electric field to be z = z0. (See figure.) You will use...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
