Answer 2

Answer:

30° .

Explanation:

Angular displacement of a body is defined as the angle between the Initial and Final positions of the body while it is moving on a circular path. It means it is the Angel through which the body moves while move on the circular path.

It is given by the Expression,

0=1/12

Where :

1: 0 represent the angle through which the body moved.

2: 1 is the length of Arc or distance traveled by the body.

3: r is the Radius.

In the similar way :

Angular displacement of the minute hand is the angle between the Initial and the final position of the minute hand while moving on the circumference of the clock.

We know that : 1 hour, minute hand moves an angel of 360°.

= In 60 minutes hand moves through an angel of 360° .

= In (12×5) minutes, minute hand moves through an angel of 360° .

= In 5 minutes minute hand moves through an angel of (360/12).

= In 5 minutes ,minute hand moves through an angel of 30° .

The angular displacement by the minute hand after minutes is 30° .
