Question

the mass of a particle at the centre of the earth is: a)zero b)slightly more at the poles c) infinite d)same as the poles

Answer 1

It would be zero. The weight of an object is the maximum at the surface of the earth. As you move the body closer to the center of the earth, the mass of the earth between the center of the earth and the body keeps decreasing. This causes the force acting from the center of the earth on the body to decrease.

YOUR ANSWER IS OPTION (A)

Answer 2

Answer:

same as pole

Explanation:

mass is independent of gravity.

its weight will differ at pole and center
