Question

Density, density, density, (a) A charge -345e is uniformly distributed along a circular arc of radius 7.00 cm, which subtends an angle of 73 degree. What is the linear charge density along the arc? (b) A charge -345e is uniformly distributed over one face of a circular disk of radius 2.20 cm. What is the surface charge density over that face? (c) A charge -345e is uniformly distributed over the surface of a sphere of radius 4.10 cm. What is the surface charge density over that surface? (d) A charge -345e is uniformly spread through the volume of a sphere of radius 2.60 cm. What is the volume charge density in that sphere?

Explanation / Answer

[H+] =hydrgen concentration is =10(-pH) =

at 4.62+0.03 = 4.65, [H+] =10-(4.65) = 2.2*10-5

at 4.62, [H+] = 2.4*10-5

at 4.62-0.03= 4.59, [H+] =10(-4.59)= 2.6*10-5

pH= 2.4*10-5 +-0.2*10-5
