An uncharged conductor has a hollow cavity inside of it. Within this cavity there is a charge of + 10 µC that does not touch the conductor. There are no other charges in the vicinity. Which statement about this conductor is true?

we have to make charge inside the conductor zero because we know that electric field inside the conductor should be zero

so, the outer surface of the conductor should contain + 10 uC of charge and the inner surface contains - 10 uC
