How do you find the net charge of a sphere
WebExplicitly calculate the value of the field at the surface of the sphere. Consider a sphere of radius R=50cm with a density of charge given by ρ (r) = αr and a total charge Q = 10*10-6 C. Determine the value of α. Determine how the electric field varies in all space. Explicitly calculate the value of the field at the surface of the sphere. 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)
