A ray is incident from a medium of refractive index 2 into a medium of refractive index 1. The critical angle is

Consider a disc of radius \(R\) and mass \(M\). A hole of radius \(\frac{R}{3}\) is created in the disc, such that the centre of the hole is \(\frac{R}{3}\) away from centre of the disc. The moment of inertia of the system along the axis pe...

Output of following logic circuit is

An object undergoing simple harmonic motion takes 0.5 s to travel from one point of zero velocity to the next such point. The angular frequency of the motion is

A hydrometer executes simple harmonic motion when it is pushed down vertically in a liquid of density \(\rho\). If the mass of hydrometer is \(m\) and the radius of the hydrometer tube is \(r\), then the time period of oscillation is

A cone with half the density of water is floating in water as shown in figure. It is depressed down by a small distance \(\delta(\ll< H)\) and released. The frequency of simple harmonic oscillations of the cone is

If \(N_A, N_B\) and \(N_C\) are the number of significant figures in \(A=0.001204 \mathrm{~m}, B=43120000 \mathrm{~m}\) and \(C=1.200 \mathrm{~m}\) respectively, then

A body is suspended from a string of length 1 m and mass 2 g. The mass of the body to produce a fundamental mode of 100 Hz frequency in the string is (Acceleration due to gravity \(=10 \mathrm{~ms}^{-2}\))

A bead of mass 400 g is moving along a straight line under a force that delivers a constant power 1.2 W to the bead. If the bead is initially at rest, the speed it attains after 6 s in \(\mathrm{ms}^{-1}\)

A mass of 1 kg falls from a height of 1 m and lands on a massless platform supported by a spring having spring constant \(15 \mathrm{~Nm}^{-1}\) as shown in the figure. The maximum compression of the spring is (acceleration due to gravity $...
