the plastic strip acquired extra protons from the charging process

protons were created as the result of the charging process

A balloon is rubbed against a student's hair and then touched to a wall. The balloon sticks to the wall due to

The balloon has a charge, so it attracts the neutral wall

The balloon is charged neutral, so is the wall, so it attracts to the wall

The balloon is charged opposite the wall, so it attracts to the wall

The wall grounds the balloon, so it sticks

A balloon is rubbed on a student's head. What occurs because of this?

Negatively charged particles move from head to balloon

Charged particles on the balloon are destroyed

Positively charged particles move from head to balloon

Charged particles from the balloon are released into the air

When a positively charged rod touches a neutral object

Electrons flow from the neutral object to the positive object

Protons flow from the positive object to the neutral object

Electrons flow from the positive object to the neutral object

An electroscope is designed to

Alleviate excess charge from a system

Determine the magnitude of an electrostatic force between charged surfaces

Analyze the relationship between gravitational and electrostatic forces

What could be the charges of the two balloons?

each balloon has opposite charge

What does "r" measure?

the distance between the two charged objects

the amount of charge carried by the objects

the amount of force between two charged objects

the constant value for forces between the objects

An electrostatic force of magnitude F exists between two metal spheres having identical charge q. The distance between their centers is r. Which combination of changes would produce no change in the electrostatic force between the spheres?

doubling q on both spheres while doubling r
