To find the time period of rotation of the Earth around its axis so that objects at the equator become weightless, we can follow these steps: ### Step 1: Understand the Forces Acting on the Object When an object is at the equator, two forces act on it: 1. The gravitational force (weight) \( W = mg \) 2. The centrifugal force due to the Earth's rotation \( F_c = m r \omega^2 \) Where: ...
