Get started for freeA spherical volume having a \(2-\mu \mathrm{m}\) radius contains a uniform volume charge density of \(10^{15} \mathrm{C} / \mathrm{m}^{3}\). (a) What total charge is enclosed in the spherical volume? (b) Now assume that a large region contains one of these little spheres at every corner of a cubical grid \(3 \mathrm{~mm}\) on a side and that there is no charge between the spheres. What is the average volume charge density throughout this large region?
(a) Find \(\mathbf{E}\) in the plane \(z=0\) that is produced by a uniform line
charge, \(\rho_{L}\), extending along the \(z\) axis over the range \(-L
Two point charges of equal magnitude \(q\) are positioned at \(z=\pm d / 2 .(a)\) Find the electric field everywhere on the \(z\) axis; \((b)\) find the electric field everywhere on the \(x\) axis; \((c)\) repeat parts \((a)\) and \((b)\) if the charge at \(z=-d / 2\) is \(-q\) instead of \(+q\).
Two identical uniform sheet charges with \(\rho_{s}=100 \mathrm{nC} / \mathrm{m}^{2}\) are located in free space at \(z=\pm 2.0 \mathrm{~cm}\). What force per unit area does each sheet exert on the other?
Find \(\mathbf{E}\) at the origin if the following charge distributions are present in free space: point charge, \(12 \mathrm{nC}\), at \(P(2,0,6) ;\) uniform line charge density, \(3 \mathrm{nC} / \mathrm{m}\), at \(x=-2, y=3 ;\) uniform surface charge density, \(0.2 \mathrm{nC} / \mathrm{m}^{2}\) at \(x=2\).
