Multiple choice

A child has two beakers. In the first beaker, he poured some drinking water and in the other, he poured some seawater. He tests the solutions with a tester and compass needle. In which case will the compass needle deflect more?

  1. The beaker with drinking water will show more deflection.

  2. Both the beakers will show the same deflection.

  3. The beaker with seawater will show more deflection.

  4. The beaker with seawater will show no deflection.

C Correct answer
Explanation

The beaker with seawater will show more deflection as seawater being salty is a better conductor. As more current flows through the seawater, the deflection shown by the needle will be more.
