A-3.07 μC charge is placed at the center of a conducting spherical shell, and a total charge of + 7.25 μC is placed on the shell itself. Calculate the total charge on the outer surface of the conductor.

4.18 μC

Explanation:

given,

charge place at the center of conducting spherical shell = - 3.07 μC

total charge place in the shell itself = + 7.25 μC

to calculate charge on the outer surface = ?

total charge on the outer surface = + 7.25 μC - 3.07 μC

= 4.18 μC

hence, the charge on the outer surface of the shell is 4.18 μC
