The Sun rises in the East and sets in the West because the Earth rotates about its axis from West to East. As the Earth rotates, different parts of the planet face the Sun, causing the appearance of sunrise and sunset. The direction of the sunrise and sunset changes throughout the year as the Earth's axial tilt and its position in its orbit around the Sun cause changes in the angle of the incoming sunlight.

However, it is important to note that the Sun does not actually rise and set, as it is a star located 93 million miles (150 million kilometers) away from the Earth. Rather, it is the rotation of the Earth that causes the apparent movement of the Sun across the sky.

Earth's Rotation

Earth's Rotation

Here are some interesting facts about Earth's rotation:

Earth's rotation period is approximately 24 hours, which is why we have a day-night cycle.
Earth's rotational velocity is not constant, and is faster at the equator than at the poles. This is due to the shape of the Earth, which bulges at the equator and flattens at the poles.
The Earth's rotational axis is tilted at an angle of approximately 23.5 degrees relative to the plane of its orbit around the Sun, which causes the changes in the seasons.
Earth's rotation causes the Coriolis effect, which is responsible for the patterns of ocean currents and wind direction.
The length of a day on Earth can change due to factors such as the gravitational influence of the Moon and other celestial bodies, as well as changes in the Earth's rotation rate.
Earth's rotation causes the Foucault pendulum, a simple pendulum that demonstrates the rotation of the Earth, to swing in a circular path instead of in a straight line.
Earth's rotation also causes the phenomenon of the diurnal parallax, which is the apparent movement of the stars across the sky due to the Earth's rotation.

These are just a few of the fascinating effects of Earth's rotation, which play a key role in shaping our planet and its environment.

An astronomical telescope consists of two converging lenses. One of them of large aperture and large focal length is called objective lens and the other one, of smaller focal length and smaller aperture is called the eyepiece. It is used to see distant objects which are not seen clearly with naked eyes. The image formed by the objective lens acts as an object for the eyepiece and the final image produced by the eyepiece is magnified.

5.
Read the following paragraph and answer the questions that follow.
In an experiment with convex lens of focal length f, the screen is fixed at a distance D from the object. A student slowly moves the lens away from the object towards the screen and finds that she is able to form sharp image of the object for two positions of the lens. The distance between these two positions of the lens is d.

A charged particle $+q$ in an electric field $\vec{E}$ experiences a force in the direction of the electric field. As a result, its kinetic energy changes. Similarly, the charged particle also experiences a force when it moves in a magnetic field $\vec{B}$. But this magnetic force is perpendicular to both velocity $\vec{v}$ of the charged particle and the magnetic field $\vec{B}$, so it cannot change the kinetic energy of the charged particle. Consider two charged particles 1 and 2 of masses $m$ and $\frac{m}{2}$ having charges $-q$ and $+2q$ respectively. They are accelerated from rest through the same potential difference $V$ and acquire kinetic energy $K_1$ and $K_2$. Then they enter in a region of uniform magnetic field $\vec{B}$ perpendicular to their velocities.
