Static electricity is caused by the imbalance between protons and electrons

• True

• False

protons are transferred from a piece of silk to a glass rod when the two are rubbed together

• True

• false

Electrical force is directly proportional to the products of two charges

• True

• False

Electric field lines goes outward from the positive charge and goes to the negative charge

• True

• False

If a rubber rod repels a pith ball, we can deduce that both objects carry alike charges

• True

• False

Two charges objects, A and B, have an equal amount of charge, they are placed at a distance of D and they repel each other with a repulsive force of F. in order to make the force become 1/9 of the initial force, then the distance should be changed into 1/9 times closer

• True

• False

The SI unit of a charge is...

• Kelvin

• Mole

Van de Graff is used to generate static electricity, while the electroscope is used to detect...

• Objects

• presence of a charged object

• Moving object/living being

• Radiation

• Protons, protons

Electron is the name of a negative charge

• True

• False
