Consider themotion of thetip of the minute hand of a clock. In onehour
a) the displacement iszero
b) the distance covered is zero
c) the average speed is zero
d) the average velocity is zero
1 \(a \&\) bare correct

A body is moving along the circumference of a circle of radius '\(R\) ' and completes half of the revolution. Then, the ratio of its displacement to distance is
1 \(\pi: 2\)
2 \(2: 1\)
3 \(2: \pi\)
4 \(1: 2\)
Explanation:
Displacement : : istance \(=\pi R: 2 R\)

A body completes one round of a circle of radius '\(R\) ' in 20 second. The displacement of the body after 45 second is
1 \(\frac{R}{\sqrt{2}}\)
2 \(\sqrt{2} R\)
3 \(2 \sqrt{R}\)
4 \(2 R\)
Explanation:
In 40 sec body completestwo revolutions.
In 5 sec it covers \(1 / 4\) th of the circle and angle traced is \(\frac{\pi}{2}\). So displacement \(s=2 R \sin \frac{\theta}{2}\)
