A student hung a magnet on a spring coil...

A student hung a magnet on a spring coil as shown in the diagram.

Next, he held another magnet under the first magnet as shown here.

What had caused the spring coil to extend ?

A

Magnet P was too heavy for the spring coil.

B

Magnet P repelled magnet Q.

C

Magnet P became stronger.

D

Magnet Q attracted magnet P.

Text Solution

Verified by Experts

The correct Answer is:
D
The unlike poles were facing each other causing the two magnets to be attracted to each other. As magnet P moved towards magnet Q, the spring coil extended.
