Question

On account of the earth rotating about its axis

• A. the linear velocity of objects at equator is greater than 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 at the earth is equal, but angular velocity is different
• D. at all places the angular velocity and linear velocity are uniform

Answer 1

Answer: (A)

$(1)$ as distance of surface is maximum from axis at equator, hence $v$ is maximum as $v=\omega \times r$
$(2)$ angular velocity is same everywhere
$(3)$ as distance of surface is maximum from axis at equator, hence $v$ is maximum as $v=\omega \times r$
$(4)$ as distance of surface is maximum from axis at equator, hence $v$ is maximum as $v=\omega \times r$
