Question

If we go above the surface of earth, the gravitational constant
(a) Remains constant
(b) Becomes zero
(c) Varies inversely to the square of the distance

Answer 1

Explanation:

Gravitational Constant Varies From Place To Place So, The Right Answer is No. (C)

Answer 2

Answer:

The correct answer is option (a) Remains constant

Explanation:

Gravitational constant is a universal constant whose value remains constant in the whole universe. If we go above the surface of the earth, the gravitational constant remains constant as it doesn't depend on anything like height or depth.

This constant appears in Newton's Gravitation law. According to this law, the gravitational force between two objects (F) is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, it can be expressed as,

F $\propto$ m₁m₂/r²

where F = Force

m₁ = Mass of the first object

m₂ = Mass of the second object

r = Distance between them

F = Gm₁m₂/r²

where G = Proportionality constant called universal gravitational constant.

Value of G = 6.67 × 10⁻¹¹ m³ kg⁻¹ s⁻²

The value of the gravitational constant G is constant and does not depend on anything.

Hence, the correct answer is option (a).
