Why is there more weight at the poles?
The equator is moving quickly as the earth’s spins, so it has a lot of centrifugal force. The centrifugal force at the poles is zero. Your total weight at sea level at the equator (gravity minus centrifugal force) is therefore 9.764 m/s2 times your mass, whereas your weight is 9.863 m/s2 times your mass at the poles.
What is the weight of a body at the Centre of Earth?
Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. At centre of earth, value of g is zero. Hence, weight is zero.
At what depth the weight of the body becomes half the weight on the surface of the earth R 6400 km?
Answer. The depth will be 3200 km. Hence, depth at which acceleration due to gravity is half will be – 3200 km.
What is the acceleration due to gravity on top of Mount Everest?
Hence, the acceleration due to gravity at a point on Mount Everest is 9.773m/s2. Note: The magnitude of acceleration due to gravity decreases as we move above the surface of the earth or down the surface of the earth.
Where does a body experience maximum weight on the earth what is the reason?
As the distance of the pole is less than the distance of the equator from the center of the earth, the force of attraction is higher on the body at poles than at the equator. Hence the weight of a body is greater at pole than at the equator.
At which part of the earth is a body to be placed to experience the maximum force of attraction?
poles
Why does a freely falling body experience weightlessness?
When in free fall, the only force acting upon your body is the force of gravity – a non-contact force. Since the force of gravity cannot be felt without any other opposing forces, you would have no sensation of it. As such, you would experience a weightless sensation.
Where will the value of G be the maximum on the earth’s surface?
The centrifugal force for the spinning of earth is maximum at the equator and vanishes at the poles. Thus, the gravitational acceleration (g) is minimum at the equator and it is maximum at the poles.
