Why did the tin plates jump off the Vaan de Graaf when it was turned.
The plates become positive (+) like the sphere and were repulsed by the similar charge.
The plates become positive (+) like the sphere and were repulsed by the opposite charge.
The plates become negative (-) like the sphere and were repulsed by the similar charge.
The plates become negative (-) like the sphere and were repulsed by the opposite charge.

What will happen when the negatively charged rubber rod comes near the neutral electroscope?
The leaves will open because the electrons will move away from the rod. Like charges repel.
The leaves will open because the protons will move toward the rod. Opposite charges attract.
The leaves will open because the protons will move away from the rod. Opposite charges repel.
The leaves will open because the electrons will move toward the rod. Like charges attract.
After the negatively charged rubber rod makes contact with the electroscope, what will happen?
The leaves stay open because electrons transferred to the electroscope and it is now negatively charged.
The leaves stay open because protons transferred to the electroscope and it is now negatively charged.
The electroscope goes back to what the neutral electroscope looks like.
