Why is the weight of a body zero?
Weight can be zero when acceleration due to gravity is zero. The value of ‘g’ is maximum on the surface of the Earth and decreases on going inside the surface or above the surface of the Earth. Thus, the weight of a body will be zero at the centre of the Earth.
Why is the weight of a body zero at the Centre of the earth 1?
g is the acceleration due to gravity. But, as the force and weight are the same. Thus, weight is zero where the acceleration due to gravity is zero. Hence, the weight of the body placed at the center of the earth is zero.
Why can weight be zero when mass Cannot be zero?
The mass of a body can be zero whereas the weight of a body can never be zero. Hence the weight of the body can be zero. Now as we know that the mass of any body does not depend on any parameter it is dependent only on the object i.e. body because mass is an intrinsic property. So the mass of a body can never be zero.
Why is the weight zero at the center of earth What is this state called?
Acceleration due to gravity becomes 0. Weight is equal to mg. At the center of the earth, you experience zero net force since every mass particle is equally pulling on you in different directions that all cancel out. Thus, your acceleration is zero and therefore your weight is 0.
Can a body has zero mass and zero weight?
It is not possible for a body to have zero mass ( no body can exist without mass ) but a body can have zero weight….. Weight = Mass × Gravitational acceleration. At the center of the earth the gravitational acceleration is 0 so multiply 0 with mass and any no. multiplied with 0 is 0 so weight can be 0.
Is weight of a body may be zero?
weight of the body is actually the gravitational force acting on it and mass of a body is the no. of particles present in it. therefore weight can be zero but mass can never be zero.
Where weight of a body is zero?
the centre of the earth
The weight of a body is zero at the centre of the earth.
How can weight of a body be zero?
Yet others define it as the magnitude of the reaction force exerted on a body by mechanisms that counteract the effects of gravity: the weight is the quantity that is measured by, for example, a spring scale. Thus, in a state of free fall, the weight would be zero.
Can weight of a body be zero?
The mass of a body is can be zero whereas the weight of a body can never be zero.
Which of mass and weight can be zero and why?
Mass can never be zero. Weight can be zero if no gravity acts upon an object, as in space. Mass does not change according to location. Weight varies according to location.
Where the weight of a body is zero?
What happens if the weight of an object is zero?
Weight is the measure of the normal contact force on a body. If this force comes out to be zero, then the weight of the object will be zero. For example, consider a person in a lift whose cable has broken. That means that it will be undergoing a free fall with a downward acceleration ‘g’.
Why is the apparent weight of a body zero during free fall?
But, during free fall you say that the only force acting on the body is its weight, yet, its apparent weight is zero… how is that so?- there is no opposite force acting on it, because it feels no stresses…? The apparent weight is zero because there is no supporting force.
What is the difference between weightlessness and weight free fall?
Free fall is when an object is falling, only being affected by the force of gravity, while weightlessness is when an object has no weight due to there being no effect from gravity (it still has mass). Weightlessness can be achieved either in space or if an equal force can be applied in the opposite direction of gravity.
Can your weight be zero in space?
In places where g is zero (like outer space) or where you are in continuous free fall (like ISS, but this condition is not fully weightless, hence it is called microgravity) or when your body’s weight is balanced by some other external force (Your weight is the force exerted by your mass on earth) your weight can be zero.
