Where G is maximum and minimum?
Value of g is maximum at the poles, thats why we may weigh more than we are in the equators. Value of g is minimum at the equator and hence we will weigh less.
What is the maximum value of g at poles?
The standard value of 9.8 m/s2 refers to Earth as a homogeneous sphere, but in reality there are many reasons for this value to range from a minimum of 9.78 m/s2 at the Equator to a maximum of 9.83 m/s2 at the poles.
Why is G zero at the Centre of the earth?
At the centre of Earth, the force due to upper half of the Earth will cancel the force due to lower half. In the similar manner, force due to any portion of the Earth at the centre will be cancelled due to the portion opposite to it. Thus, the value of g is zero at the centre of Earth.
At what height the value of g is zero?
Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·s−2 per 3,200 km.)
What is difference between weightlessness and free fall?
Answer. Weightlessness is the complete or near-complete absence of the sensation of weight. This is also termed zero-g, although the more correct term is “zero g-force”. In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it.
Where is the true weight of the body zero?
The true weight of a body will be zero where the gravitational effects are nil, e.g., at the centre of earth.
Why mass can never be zero even when force is zero?
Whereas on the other hand mass cannot be zero because mass is an intrinsic property and hence it depends upon the object alone and not on other factors. Thus mass of a body cannot be zero.
Under what conditions does your weight become zero?
Answer Expert Verified so when g= acceleration due to gravity becomes zero then weight will be zero. 3. In space, where zero gravity is there.
Where is the weight of a body greatest?
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.
How much would a 200 pound man weigh on moon?
In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds. Your weight on the Moon would only be 33 pounds.
