Question

ramesh today asked his teacher why the value of gravitational acceleration is higher at the poles than at the equator. (a.) becouse the radius of the earth is less at the poles. (b.) becouse the radius of the earth is greater at the pole. (c.) becouse the radius of the earth is less at the equator. (d.) the gravitational acceleration at the poles and the equator remains the same.​

Answer 1

$\Large{\boxed{\underline{\bf{AnswEr:-}}}}$

❍ (a) because the radius of the earth is less at the poles. (✔)

$\Large{\underline{\underline{\bf{ReaSon:-}}}}$

✪ The earth is not a perfect square. its radius is more at Equator than the poles. so, value of 'g' is greater at the poles than the value at the equator. (For calculation, we use same value of g i.e., 9.8 m/s².

More To Know!

☞ Value of g also depends on the position of the object. Below and above the earth surface value of g goes on decreasing. In mines (below the earth surface) and mountains (above the earth surface) value of g is lesser than the value on earth surface.

Answer 2

$\mathcal{\huge{\fbox{\red{Correct\:Question\:?}}}}$

✴ Ramesh today asked his teacher why the value of gravitational acceleration is higher at the poles than at the equator.

(a.) Because the radius of the earth is less at the poles.

(b.) Because the radius of the earth is greater at the pole.

(c.) Because the radius of the earth is less at the equator.

(d.) The gravitational acceleration at the poles and the equator remains the same.

$\mathcal{\huge{\fbox{\green{Answer:-}}}}$

Option.a) Because the radius of the earth is less at the poles.

$\mathcal{\large{\fbox{\purple{Conceptual\:Information:-}}}}$

• The Earth is not exactly spherical it's ovaluated circle its little bit like a "squashed" sphere, the radius at the equator slightly larger than the radius at the poles which effects the centripetal acceleration.

• It effects slightly increase in weight at the poles .

• The gravitational force depends on distance and slightly decreasing it at the equator.

• The centripetal acceleration is less at the equator than at the poles.
