Under what conditions a body becomes weightless? |
Answer» Weight of a body is nothing but the force with which it is attracted towards the centre of earth. Force = Mass × Acceleration W = m × g Since, we have Force = Weight = W and acceleration is acceleration due to gravity or g. A body becomes weightless when g becomes zero and this happens when acceleration due to gravity becomes zero and thus body becomes weightless. Example: At centre of earth, far away from earth’s surface, freely falling body |
