Negative

Explanation:

If a negatively charged object is used to charge a neutral object by induction, then the neutral object will acquire a positive charge. And if a positively charged object is used to charge a neutral object by induction, then the neutral object will acquire a negative charge:

We have a neutral sphere

1) Electrons are attracted to the positive charge

2) Electrons enter the sphere from ground, attrated to the + charge in the sphere

3) The sphere has an excess of e - having entered from the ground

4) Electrons redistribute uniformly
