The ratio of the radius of gyration of a thin uniform disc about an axis passing through its centre and normal to its plane to the radius of gyration of the disc about its diameter is:

The angular speed of a fly wheel moving with uniform angular acceleration changes from $1200\text{rpm}$ to $3120\text{rpm}$ in $16\text{seconds}$. The angular acceleration in ${\text{rad/s}}^2$ is:

An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric and isochoric. The curve which represents the adiabatic process among 1, 2, 3 and 4 is:

Two hollow conducting spheres of radii $R_1$ and $R_2$ ($R_1\gg R_2$) have equal charges. The potential would be:

When light propagates through a material medium of relative permittivity ${ϵ}_r$, and relative permeability ${\mu }_r$, the velocity of light, $v$ is given by ($c$ - velocity of light in vacuum):
