Question

On account of the rotation of earth about its axis:

• A. the linear velocity of objects at equator is greater than that at other places
• B. the angular velocity of objects at equator is more than that of objects at poles
• C. the linear velocity of objects at all places on the earth is equal, but angular velocity is different
• D. the angular velocity and linear velocity are uniform at all places

Answer 1

The correct option is A the linear velocity of objects at equator is greater than that at other places

the relation between linear velocity and angular velocity is $V=r\omega$ where r is the distance of the particle from the axis

and $\omega$ is the angular velocityof the earth which will be same for all the particles

so linear velocity of objects at equator is greater than that at other places as r will be highest

so correct option is$A$
