+5.20 µC

Explanation:

Given that

Charge = -5.20 µC and radius = 5.40 cm.

Insert a + 10.4 - µC charge at the center of the sphere

As we know that according to Gauss's theorem electric field inside the metal is zero.

When + 10.4 µC charge insert but the total charge on the sphere should be - 5.20 µC. So the charge on the outer surface of the sphere will be + 5.20 µC.
