The table provided shows data collected by students during an investigation of two electromagnets. Which of the following conclusions is supported by data on the table?
When two electromagnets are of like charges, they attract each other.
Electromagnets that repel each other have more force than those that attract each other.
The greater the charges of two electromagnets, the greater the size of the force.
If the charge on one magnet is positive, the charge on the other must be negative.
This table shows the magnitude of electromagnetic force exerted by two electromagnets on each other as the distance between the two electromagnets is varied. The data on the table provide evidence for which of the following conclusions?
The force between any two magnets is always constant, regardless of distance.
As distance between electromagnets increases, the electromagnetic force also increases.
The smaller the distance between two electromagnets, the greater the force.
The force between two magnets depends only on the charge of the electromagnets.
What will happen as an electron (-) gets closer to a proton (+)?
The repulsion will be stronger.
The attraction will be stronger.
The attraction will be weaker.
Nothing will happen to the electric field.
