A solld cylinder of mass \(2 \;\mathrm{kg}\) and radius \(50 \;\mathrm{cm}\) rolls up an inclined plane of angle inclination \(30^{\circ}\). The centre of mass of cyllnder has speed of \(4 \;\mathrm{m} / \mathrm{s}\). The distance travelled by the cyllinder on the incline surface will be ......\(m\)

Two rotating bodies \(A\) and \(B\) of masses \(m\) and \(2\,m\) with moments of inertia \(I_A\) and \(I_B (I_B> I_A)\) have equal kinetic energy of rotation. If \(L_A\) and \(L_B\) be their angular momenta respectively, then

In Young's double slit experiment, using monochromatic light of wavelength \(\lambda\), the intensity of light at a point on the screen where the path difference is \(\lambda\), is K units. The intensity of light at a point where the path difference is \(\frac{\lambda}{3}\) will be :

An electromagnetic wave of wavelength \(\lambda\) is incident on a photosensitive surface of negligible work function. If \(m\) mass is of photoelectron emitted from the surface has de-Broglie wavelength \(\lambda_{\mathrm{d}}\), then

A box of mass 15 kg is kept on the floor of a stationary trolley. The coefficient of static friction between the box and the trolley is 0.12. Keeping the box in stationary state over the trolley, the maximum acceleration with which the trolley can be moved horizontally in \(m s ^{-2}\) is :
\(\left(g=10 m / s ^2\right)\)

Two gases \(A\) and \(B\) are filled at the same pressure in separate cylinders with movable pistons of radius \(r_A\) and \(r_B\), respectively. On supplying an equal amount of heat to both the systems reversibly under constant pressure, the pistons of gas \(A\) and \(B\) are displaced by 16 cm and 9 cm , respectively. If the change in their internal energy is the same, then the ratio \(\frac{r_A}{r_B}\) is equal to

Given below are two statements: one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A\): The potential ( \(V\) ) at any axial point, at \(2 \mathrm{~m}\) distance ( \(r\) ) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, \(4 \times 10^{-6} \mathrm{C} \mathrm{m}\), is \(\pm 9 \times 10^3 \mathrm{~V}\).
