The weight of the body at the center of the Earth is:
Correct answer: A. Zero
- A. Zero
- B. Infinite
- C. Same as on the surface
- D. None of these
Explanation
The following is the solution: Because g at the center of the Earth is zero So weight = mg is also zero. This is because, at the center, the gravitational forces from all directions cancel each other out, resulting in a net gravitational force of zero.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.

A 2 kg body falls from infinity to the surface of earth. What will be the kinetic energy of the body on reaching the surface of Earth (Assume escape velocity to be 104 ms-1)?
The two moving particles collide and clump together on a smooth horizontal surface. The following statements are given below:
If the speed of rotation of Earth about its axis increases, then the weight of the body at the equator will:
When you move from the equator to the poles, the value of acceleration due to gravity (g):
Average density of the Earth:
The binding energy of a particle of mass m with a planet, when it is on the planet's surface, is 1/2mv02. A tunnel is dug along the diameter of the planet and the particle is dropped into it from the surface, when the body reaches the center of the planet, its speed is:
