(a) zero (b) slightly more than at the poles (c) infinite (d) same as at the poles

Answer 1

hello there your answer is
option a zero
hope it helps you...

Answer 2

The mass of a particle at the centre of the Earth is same as at the poles. ( option d)

- The mass is not dependent on the gravitational acceleration of a place.

- That's why mass is always constant in any part of our planet.

- Unlike weight the mass doesn't increase or decrease when the altitude is changing.

- That's why a substance of mass X at the poles is same of mass X in the centre of the earth too.
