Question

# The value of 'g'.

- Increases as we go from pole to equator
- Decreases as we go from pole to equator
- Remains constant
- It is more at the equator and less at the poles.

Hint:

### The gravity is directly proportional to the distance from the centre.

## The correct answer is: Decreases as we go from pole to equator

### The correct option is b)Decreases as we go from pole to equator.

The Earth is not a perfect sphere, so gravity will always change as you move from one place to another. However, it is maximum near the center. Because the Earth is an ellipse rather than a perfect sphere, Earth's gravity is greatest at the poles. Also, the equator is farther from the Earth's center of gravity than the poles.

Therefore, the value of g increases as you go from the equator to the poles.

### Two objects of different masses falling freely near the surface of the earth would:

The correct option is** a)Have same velocities at any instant.**

In free fall, velocity depends only on acceleration due to gravity. Acceleration due to gravity is independent of the mass of the object. Therefore, the gravitational pull of the moon applies the same acceleration to both objects. Therefore, it will always have the same velocity regardless of mass. The force depends on the mass, and since the bodies have different masses here, no two will experience the same force.

### Why does the earth not seem to move towards an apple falling towards it?

The correct option is **c)The acceleration gained by the earth is not sufficient for its motion to be apparent.**

Acceleration is inversely proportional to mass, so gravitational acceleration can be ignored.

The apple falls to the earth, but the earth does not move towards the apple because acceleration is inversely proportional to mass. The Earth's mass is very large compared to the apple, so the acceleration towards the apple is negligible.

### The pull exerted by the Earth on a body of mass 1 kg is ___ N.

The correct option is c)9.8.

From Newton's law of universal gravitation, we know that the gravitational force between objects is given by the following formula:

$Mass of earth=M= 6.0×10kg$

$m=1kg$

$R= 6.4 x 106$

$G= 6.67 x 10-11 Nm2 /kg$

$Substituting the values we get,$

$F=9.8 N$

### Gravitational force attracts the earth and the moon to each other. The earth attracts the moon with the following force:

The correct option is b)Same as that exerted by the moon.

Let m and M be the masses of the moon and the earth separated by a distance r.

Force of attraction that earth exert on moon=

Force of attraction that moon exert on earth=

This shows that they both exert same pressure on each other.
