If an object of height \(6 \mathrm{~cm}\) is viewed through a liquid of refractive index \(\frac{4}{3}\) vertically at a depth of \(10 \mathrm{~cm}\). Then what will be its apparent height and apparent distance from the surface of liquid.

Consider a rod of mass \(M\) and length \(L\) pivoted at its centre free to rotate in a vertical plane. The rod is at rest in the vertical position. A bullet of mass \(M\) moving horizontal at a speed \(v\) strikes and gets embedded in one ...

A particle of mass \(m\) is allowed to fall freely under gravity from a point \(P\) as shown in the figure. If the vector position \(Q\) of the particle from the origin is represented by \(\mathbf{r}\), the magnitude of torque acting on the...

When in \(p\)-\(n\) junction diode, \(p\) is connected to the positive terminal and \(n\) is connected to the negative terminal, then it is

Which of the following is arranged in forward bias?

One end of a spring of force constant \(k\) is fixed to a vertical wall and other to a body of mass \(m\) resting on a smooth horizontal surface. There is another wall at a distance \(x_0\) from the body. The spring is then compressed by $$...

A quantity $X$ is given by \(\frac{\varepsilon_0 A}{L} \frac{\Delta V}{\Delta t}\), where \(\varepsilon_0\) is the permittivity of free space, \(L\) is the length, \(A\) is area, \(\Delta V\) is the potential difference and \(\Delta t\) is ...

A person is standing at some point between two parallel cliffs (not exactly at the centre). He claps, and hears two echoes: the first after \(1 \mathrm{~s}\) and the second after \(2 \mathrm{~s}\). If the speed of sound in air is $$330 \mat...

A toy gun uses a spring of force constant \(k\). When charged before being triggered in the upward direction, the spring is compressed by a distance \(x\). If the mass of the shot is \(m\), on being triggered it will go upto a height of

A particle of mass \(m\) is moving in a horizontal circle of radius \(r\) under a centripetal force given by \(\left(-k / r^2\right)\), where \(k\) is a constant. Then
