A large spherical mass M is fixed at one position and two identical masses m are kept on a line passing through the centre of M (see figure). The point masses are connected by a rigid massless rod of length l and this assembly is free to mo...

An ideal monoatomic gas is confined in a horizontal cylinder by a spring loaded piston (as shown in the figure). Initially the gas is at temperature T1, pressure P1 and volume V1 and the spring is in its relaxed state. The gas is then heate...

Consider two different metallic strips (1 and 2) of same dimensions (length l, width w and thickness d) with carrier densities n1 and n2, respectively. Strip 1 is placed in magnetic field B1 and strip 2 is placed in magnetic field B2, both ...

Consider two different metallic strips (1 and 2) of the same material. Their lengths are the same, widths are w1 and w2 and thickness are d1 and d2, respectively. Two points K and M are symmetrically located on the opposite faces parallel t...

In plotting stress versus strain curves for two materials P and Q, a student by mistake puts strain on the y-axis and stress on the x-axis as shown in the figure. Then, the correct statements is/are

Two spheres P and Q for equal radii have densities \(\rho\)1 and \(\rho\)2, respectively. The spheres are connected by a massless string and placed in liquids L1 and L2 of densities \(\sigma\)1 and \(\sigma\)2 and viscosities \({\eta _1}\) ...

A spherical body of radius R consists of a fluid of constant density and is in equilibrium under its own gravity. If P(r) is the pressure at r (r < R), then the correct option(s) is(are)

The densities of two solid spheres A and B of the same radii R vary with radial distance r as \({\rho _A}(r) = k\left( {{r \over R}} \right)\) and \({\rho _B}(r) = k{\left( {{r \over R}} \right)^5}\), , respectively, where k is a constant. ...

The energy of a system as a function of time t is given as E(t) = \({A^2}\exp \left( { - \alpha t} \right)\), where \(\alpha = 0.2\,{s^{ - 1}}\). The
measurement of A has an error of 1.25 %. If the error in the measurement of time is 1.50 ...

Four harmonic waves of equal frequencies and equal intensities I0 have phase angles 0, \({\pi \over 3},{{2\pi } \over 3}\) and \(\pi\). When they are superposed, the intensity of the resulting wave is nI0. The value of n is
