Apoint charge q 6.5 x 10 12 c is placed at the center of a spherical conducting sh ell of surface of the conductor is directed radially outward and has magnitude 7.5 n/c. ner radius 3.7 cm and outer radius 4 6 cr ti e elect field use above the (a) what is the charge density (in c/m2) on the inner surface of the shell? (b) what is the charge density (in c/m2) on the outer surface of the shell? c/m2 (c) what is the net charge (in c) on the conductor?

iron would move it is magnetic there is a mag field around the current in the wire

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
