Answer

(a) Small sphere -Positive charge (b) Inner surface of hollow sphere - Negative charge (c) Outer surface of hollow sphere - Positive charge.

Work Step by Step

The small sphere will be positively charged due to charge transferred by wire. This positive charge will induce a negative charge on the inner surface of hollow sphere and as hollow sphere is neutral so, there will be a positive charge on outer surface of hollow sphere. Hence, (a) Small sphere -Positive charge (b) Inner surface of hollow sphere - Negative charge (c) Outer surface of hollow sphere - Positive charge.
