weight of an object is minimum when it is placed at the center of the earth because when an object is in the center ,it experiences gravitational pull from all the sides.thus the net weight of an object remains to be zero.

Possibly, but given that the centre of the Earth is unreachable and a ball of metal anyway, a more useful and achievable location for weightlessness is in Space!
The weight of an object on Earth is influenced by the mass of the object and the acceleration due to gravity. Weight is calculated by multiplying an object's mass by the acceleration due to gravity (9.8 m/s^2 on Earth). Therefore, variations in either mass or gravity can affect an object's weight on Earth.
No, it is used to find the weight or mass of an object.
An object doesn't have a single, definite weight. Its weight depends on where it is and what other masses are nearby, so it can change. You probably know that whatever your weight is on the Earth, it would be only 1/6 as much on the moon, so you're familiar with the idea that 'weight' can change. The Earth has one weight from being 238,000 miles from the moon, and a different weight from being 93 million miles from the sun.
Weight is the force of gravity acting on an object's mass, not air pressure. Air pressure is the force exerted by the atmosphere on objects. Weight depends on the mass of the object and the acceleration due to gravity, while air pressure depends on the density of air and the height above sea level.
Even though feathers are light and rocks are heavy, when 100 kilograms of each are placed on a scale, they will exert the same downward force due to gravity. Weight is a measure of the force of gravity on an object, so in this case, both the feathers and rocks will weigh the same.
The weight of an object will be minimum at high point like mountain. This is because weight depends on acceleration due to gravity and acceleration due to gravity is inversely proportional to the square of distance from center of earth to the object. As high places like mountain is far from earth center, there is minimun weight. But at the center of earth the weight becomes null as gravity pull takes place in all direction from the center.
inertia
True. According to Archimedes' principle, an object placed in a fluid will experience a buoyant force equal to the weight of the fluid it displaces. If this buoyant force is equal to the weight of the object, the object will float.
The normal force exerted by the surface on the object is straight up and is equal in magnitude to the weight of the object.

"buoyancy"
The upward push on an object by liquid or gas it is placed in is its buoyant force. This force is equal to the weight of the fluid displaced by the object.
When an object is placed in water, it will experience a buoyant force equal to the weight of the water displaced. If the object's density is less than that of water, it will float. If it is greater, it will sink.
Buoyant force is an upward force that fluids exert on any object placed in them. It is equal to the weight of the fluid that the object displaces.
