"'=.1 A thin, horizontal square copper plate has a length of 8.63cm and is charged with 2.54 x 108 electrons. If the electrons are uniformly distributed on the surface, calculate the value of the electric field (with the upward direction positive) 2.45mm above the centre of the top surface of the plate.

Tries 2/10 Previous Tries w a The gure below shows a solid metal sphere at the centre of a hollow metal sphere. The radius of the solid metal sphere is 4.81cm, the inner radius of the hollow sphere is 9.6cm, and the outer radius of the hollow sphere is 11.5cm. The electric field (shown on the diagram) inside the hollow sphere, at a distance of 6.36cm from the centre of the solid metal sphere, has a magnitude of 14920N/C. The strength of the electric field at a point 175cm from the centre of the solid metal sphere is also 14920N/C, Conducting spheres <_.. e what is the total charge on exterior of inner sphere incorrect. tries previous inside surface hollow u a line positive formed into semicircle radius r="58.2cm," as shown in figure below. per unit length along described by expression m9 aocose. calculate value constant a0. submit answer magnitude force placed at center curvature. : y ipa cylindrical shell and has its uniformly distributed curved surface. electric field point radially outward from axis midpoint use approximate relations to find net shell. i: submitanswer measured n you are correct. your receipt no. w>
