A33 uc point charge is at the center of a hollow ungrounded thin metallic spherical shell. the shell has a net charge of + 4.0 uc . calculate the electric charge on the inner and outer surface of the shell.

Explanation:

The charge at the centre that is 33 uC will induce -33 uC on the inner surface and + 33 uC charge on the outer surface of the shell. Since the shell has a net charge of +4 uC,the outer surface must have +37 uC so the shell have net charge of + 4uC .

outer surface +37 uC

inner surface -33 uC

net charge on the shell = +4uC

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
