8. Which of the following is a true statement
describing how a van de Graaf generator
works?
A. Negative charges are deposited on the
belt, which deposits positive charges
on the metal ball.
B. Positive charges are deposited on the
belt, which deposits negative
charges on the metal ball.
C. Negative charges are deposited on the
belt, which deposits negative charges
on the metal ball.
D. Positive charges are deposited on the
belt, which deposits positive
charges on the metal ball.

Answer 1

Answer:

A. negatively charged are deposited on the belt, which deposits positive charges on the metal ball.

Explanation:

Negatively charged ions are injected at one end of thebelt towards the high potntial terminal, where they are acclerated by attractive forces towards the terminal. When the particles reach the terminal, they are stripped of some electrons to make them positively charged.

Answer 2

A negative charge is deposited on the belt, which induces a positive charge on the metal ball. Option A is correct.

Van de Graaf generator:

It is an electrostatic generator that accumulates electric charge on a hollow metal globe on the top of an insulated column using a moving belt.

• This generator creates very high electric potentials.
• The generator produces very high voltage DC electricity at low current levels.

Therefore, a negative charge is deposited on the belt, which induces a positive charge on the metal ball.
