Question

# The value of gravitational acceleration is:

- More at equator
- More at poles
- Same at poles and equator
- It remains zero at poles

Hint:

### The lesser the distance from the centre of the earth the more will be the gravitational force.

## The correct answer is: More at poles

### The correct option is b)More at poles.

The earth is not a perfect sphere. It flattens at the poles and bulges at the equator. The earth bulges at the equator due to the centrifugal force of the earth's rotation. Gravity is known to be inversely proportional to the square of the distance from the center of the Earth. The distance from the poles to the center of the Earth is less than the distance from the equator to the center of the Earth. Therefore, acceleration due to gravity is greater at the poles than at the equator.

### 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.
