At a point $A$ on the earth’s surface the angle of dip, $\delta =+25^{\circ }$. At a point $B$ on the earth’s surface the angle of dip, $\delta =-25^{\circ }$. We can interpret that:

The total energy of an electron in an atom in an orbit is $-3.4\text{eV}$. Its kinetic and potential energies are, respectively:

In total internal reflection when the angle of incidence is equal to the critical angle for the pair of media in contact, what will be angle of refraction?

The work done to raise a mass $m$ from the surface of the earth to a height $h$, which is equal to the radius of the earth, is:

When an object is shot from the bottom of a long smooth inclined plane kept at an angle $60^{\circ }$ with horizontal, it can travel a distance $x_1$ along the plane. But when the inclination is decreased to $30^{\circ }$ and the same object is shot with the same velocity, it can travel $x_2$ distance. Then $x_1:x_2$ will be:
