Astronomical telescopes and terrestrial telescopes have a number of similarities, including:

Optical Design: Both types of telescopes use similar optical designs, such as the refracting telescope, which uses a lens to focus light, or the reflecting telescope, which uses a curved mirror to reflect light. This means that the basic principles of how the telescopes work are the same, regardless of whether they are used to observe objects in space or on Earth.
Magnification: Another similarity between astronomical and terrestrial telescopes is that both are designed to magnify distant objects. This is achieved through the use of eyepieces, which allow the observer to see a magnified image of the object being observed. The level of magnification that can be achieved depends on a number of factors, including the size of the lens or mirror and the distance between the lens or mirror and the eyepiece.

A wire of length $L$ is bent round into (i) a square coil having $N$ turns and (ii) a circular coil having $N$ turns. The coil in both cases is free to turn about a vertical axis coinciding with the plane of the coil, in a uniform, horizontal magnetic field and carry the same currents. Find the ratio of the maximum value of the torque acting on the square coil to that on the circular coil.
