Question

Assertion: The acceleration due to gravity increases with height above the earth's surface. Reason: Gravitational force decreases with height

Answer 1

Explanation:

Assertion: The acceleration due to gravity increases with height above the earth's surface. Reason: Gravitational force decreases with height. ... Reason: The sun always attracts the earth with the same force.

Answer 2

Gravitation

Assertion is incorrect while reason is correct.

The gravitational force decreases as height increases and vice versa because  $g__h=g(1+\frac{h}{R})^{-2}$

Where ,

$g__h$= acceleration due to gravity at height h.

R is the radius of Earth

The value of 'g' depends on

• altitude above the earth surface
• depth below the earth surface
• shape of earth
• rotational motion of earth.

The acceleration due to gravity  is the acceleration gained by any object due to force of gravitation acting on it.
