The correct statement is:
**Force of gravity is affected by the masses of the objects and the distance between their centers.**
This is based on Newton's Law of Universal Gravitation, which states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

The correct statement is:
**The balloons will push away from each other.**
Since both balloons are negatively charged, they will experience a repulsive force and will move away from each other. Like charges repel, while opposite charges attract.

The correct answer is:
**Magnetic.**
An electrical current produces a magnetic force, as described by Ampère's circuital law and the principles of electromagnetism. When an electric current flows through a conductor, it generates a magnetic field around it.

The correct answer is:
**The force of gravity would double.**
According to Newton's Law of Universal Gravitation, the force of gravity \( F \) between two masses \( m_1 \) and \( m_2 \) separated by a distance \( r \) is given by the formula:
\[ F = G \frac{m_1 m_2}{r^2} \]
If the mass of Earth \( m_1 \) doubles (while the mass of the Sun \( m_2 \) and the distance \( r \) remain constant), the gravitational force \( F \) will also double.

The correct answer is:
**The balloon’s charge became negative, and the hair’s charge became positive.**
When the student rubs the balloon on his hair, electrons are transferred from the hair to the balloon. This results in the balloon gaining extra electrons and becoming negatively charged, while the hair loses some electrons and becomes positively charged. This difference in charge creates an attractive force between the balloon and the hair, causing the balloon to stick to the hair.

The correct answer is:
**Evenly distributed on the ball’s surface.**
When the negatively charged plastic rod touches the rubber ball, electrons from the rod are transferred to the ball, making the entire ball negatively charged. Because like charges repel and the charges are free to move, they will spread out evenly across the surface of the ball, resulting in an even distribution of negative charges.
