Which subatomic particle carries a negative charge?

Which subatomic particle cannot be transferred? Select all that apply.

• neutron

• proton

• electron

• megatron

If the statement is correct, write TRUE. Otherwise, replace the underlined word to make the answer correct.

Opposite forces attract, while like charges repel.

If an object rubs against another object and it gains a negative charge, which statement is FALSE?

• The object gained electrons.

• The object created a negative charge through friction.

• The object is lower in the triboelectric series.

• The object has more electrons than protons.

Which of the following is TRUE about voltage?

• Voltage is defined as electric potential difference. It creates a pathway for charges to flow.

• Voltage pushes the charges to flow through the open circuit.

• Voltage is the difference in electric potential energy between 2 locations when work is done.

• The closer a location is to the source charge, the lower the electric potential energy.

Shown is a simple diagram of a circuit. Label the parts.
