It better to ask "what is the mass of planet earth?" Approx. 6,000,000,000,000,000,000,000,000. The measurement of the planet's weight is derived from gravitational attraction that the Earth has for objects near it. Any two masses have a gravitational attraction for one another. The attraction however is extremely slight. From the measurement you this attraction of the two planets you can determine the mass of the two objects.
Newton showed that, for spherical objects, you can make the simplifying assumption that all of the object's mass is concentrated at the center of the sphere. The following equation expresses the gravitational attraction that 2 spherical object have on one another: F=G*M1*M2/R2.
R is the distance separating the 2 objectsG is a contant that is 6.67259x10(11)M(3/s2 kg.M1 & M2 are the 2 masses that are attracting each otherF is the force of attraction between them
The radius of the Earth is 6,400,000 meters (6.999,125 yards).

Is the weight of a body constant at all places on the earth?
The weight of a person is not constant at all places on the Earth. The weight becomes zero at the center of the earth or far away from the Earth.
Person sitting in an artificial satellite of the earth have?
... a feeling as if his weight is zero, because he is constantly falling around the Earth in the satellite's orbit..
Where on earth would the weight of a body be zero?
w=mg gravity is zero at centre of earth then g=0 and w=m(0) =0 so weight is zero
Is an orbiting astronaut subject to zero gravitational force?
The fact that he is orbiting means he is being held by the gravitational force of the Earth. If not for that, he would be headed out of the solar system.
How do you convert weight on earth to weight on mars?
Multiply Earth weight by 0.379 .
At what height from the earth the weight of an object become half of the weight on earth?
zero
What is weight of earth?
AS WE KNOW, that there is the force of gravity at the center of Earth, if every part or portion of earth has its weight then net weight of the earth will be zero........
Where on the earth would the weight of body be zero why?
on the centre of the earth.
What is weight of the body at the center of the earth?
Zero
Is the weight of a body constant at all places on the earth?
The weight of a person is not constant at all places on the Earth. The weight becomes zero at the center of the earth or far away from the Earth.
What will be the weight of a human inside a spacecraft that is revolving around the earth and why?
Zero.
Does weight act towards the centre of the earth?
Yes, at the center it becomes zero.
What is the value of Earth's gravitational field at the center of the Earth?
In the cavity at the center of the Earth, your weight would be zero, because you would be pulled equally by gravity in all directions. - The gravitational field of Earth at its center is zero.
What will be our Weight at center of earth if it was hollow sphere?
Theoretically, Zero. The gravitational pull of the earth on you (which is the definition of weight), whether the earth is solid or hollow, is the same in all directions because it is spherically symmetrical. These forces cancel each other out, leaving you with zero net weight. In real life, the earth is not a perfect sphere, but this model describes the situation adequately.
What will be the weight of the man standing on weighting machine and freely fall?
Zero relative to the weighing machine. His same weight relative to the earth.
Person sitting in an artificial satellite of the earth have?
... a feeling as if his weight is zero, because he is constantly falling around the Earth in the satellite's orbit..
Where does a body have least weight equator or earth centre?
In the middle of the earth is where an object has the lightest weight. The weight is zero. The reason is that the mass of the object is pulled equally in all directions so all the forces cancel out.
