Static electricity can attract and repel.
a. true
b. false

True. Static electricity can both attract and repel. This is because of the imbalance of electrical charges within or on the surface of particular materials.  

This type of electricity is a contrast of current electricity which mostly flows through wires and other conductors to transmit energy directly. Static charges can be created when two surfaces contact and separate where at least one of the surfaces contains a high resistance of electric current.
