Answer:
Energy conversion in flashlight.
Explanation:
When the switch of a flashlight is on, then the batteries inside them will be connected in a circuit and chemical energy from the batteries will be converted into electrical energy and then the electrical energy will be converted into light energy.
Light energy is also called electromagnetic energy.
Hence, among the given options the correct one is the first option that is:
1. Electrical energy into electromagnetic energy is the answer.
The radius of the track in the circular motion is 0.164 mm.
<h3>Magnetic force of the of charge</h3>The magnetic force of the charge is calculated as follows;
F = qvB
<h3>Centripetal force of the charge</h3>The centripetal force experienced by the charge is calculated as follows;
The radius of the track is calculated as follows;
Thus, the radius of the track in the circular motion is 0.164 mm.
