Acharge -364e is uniformly distributed along a circular arc of radius 6.10 cm, which subtends an angle of 56o. what is the linear charge density along the arc? (b) a charge -364e is uniformly distributed over one face of a circular disk of radius 4.70 cm. what is the surface charge density over that face? (c) a charge -364e is uniformly distributed over the surface of a sphere of radius 5.00 cm. what is the surface charge density over that surface? (d) a charge -364e is uniformly spread through the volume of a sphere of radius 4.10 cm. what is the volume charge density in that sphere?
