Oriana touches a positively charged metal plate to a neutral metal sphere. How does the charge of the metal

sphere change?

It has a negative charge inside of the sphere.

It has an excess of negative charge.

It has a positive charge inside of the sphere.

It has an excess of positive charge.

Explanation:

It has a positive charge inside of the sphere.

Since the metal is positively charged it must be deficient in electrons. Whereas in a neutral body there is equal number of electron and proton. In a material only electrons can flow. When a neutral sphere is brought in touch with the metal plate, electrons will begin to flow from the sphere to the metal plate. Hence, the sphere will acquire positive charge.
