The value of g inside the Earth is directly proportional to the distance from the centre of the Earth. Hence, g decreases as we go down into the Earth till it becomes zero at the centre of the Eart..

We know that whenever an object is dropped from a height, it falls towards the Earth. Similarly, when an object is projected vertically upwards, it goes up but after attaining a certain height, it starts falling down. It is the force of gravitation which pulls the object..

When an object is placed at infinity, the rays coming from it are parallel to each other. Let us consider two rays, one striking the mirror at its pole and the other passing through the centre of curvature. The ray which is incident at the pole gets reflected according to the law of refl..

Here, we consider a ray of light which is parallel to the principal axis and another ray passing through the centre of curvature. The ray which is parallel to the principal axis passes through the focus and the ray which passes through the centre of curvature retraces its path. The reflected rays ..
