Weight is the force that gravitational attraction of earth exerts towards the center of earth = mg
At the equator, an additional centripetal force acts towards it outside which is equal to mω²R = 10 × (2πT)² × (6.4 × 10⁶) = 0.33N
Hence, the net force on body at the equator = Recorded weight = mg − mω²R = 100N − 0.33N = 99.66N
