WebElectric Field: Sphere of Uniform Charge. The electric field of a sphere of uniform charge density and total charge charge Q can be obtained by applying Gauss' law. Considering a Gaussian surface in the form of a sphere at radius r > R, the electric field has the same magnitude at every point of the surface and is directed outward. WebHere you have to be careful about Ex (net) and Ey (net) they are the resolved components that is Ey (net)=Ey (from 1st charge)±Ey (from 2nd charge).The sign will depend on directon.If you only have one charge then Ey (net)=Ey (of the charge). In the video Ey= (sin58.1)2.88=2.30N/C but it will get cancelled out by other charge Comment ( 2 votes) how to stay awake without coffee or tea

WebAlthough the mass of a proton is much larger than that of an electron, the magnitudes of their charges are equal. If an object has more protons than electrons, then the net charge on the object is positive. If there are more electrons than protons, then the net charge on the object is negative. http://hyperphysics.phy-astr.gsu.edu/hbase/electric/elesph.html WebFeb 9, 2016 · Explanation: When spheres A and B touch their total charge of ( − 6q) + ( −9q) = −15q will be equally split between them, so they will each have a charge of −7.5q. When sphere C is touched to sphere A, the total charge of ( −7.5q) + 0q = −7.5q will again be evenly shared between them, so they will each be at −3.75q. react phantom flyknit
