Forces at a Distance

A student claims that the two magnets have a magnetic field that exists between them. What will occur that will support the student's claim?

• The magnets will repel each other as the closest poles have like charges.

• The magnets will repel each other as the closest poles have opposite charges.

• The magnets will be attracted to each other as the closest poles have like charges

• The magnets will be attracted to each other as the closest poles have opposite charges

Why doesn’t the gravitational pull between the Sun and the planets cause the planets to fall into the Sun?

• The background stars pull back on the planets.

• The Sun’s magnetic fields are pushing out.

• The speed of the planets flings them out.

• The weight of the space ship on planet Y will be greater than the weight of the space ship on planet X.

• The mass of the space ship on planet X will be greater than the mass of the space ship on planet Y.

• The weight of the space ship on planet X will be greater than the weight of the space ship on planet Y.
