In a Meter Bridge experiment, null point for an unknown resistance is measured. Now, the unknown resistance is put inside an enclosure maintained at a higher temperature. The null point can be obtained at the same point as bef...

Which one of the following statements is WRONG in the context of X-rays generated from a X-ray tube?

Two beams of red and violet colours are made to pass separately through a prism (angle of the prism is 60\(^\circ\)). In the position of minimum deviation, the angle of refraction will be :

A spherically symmetric gravitational system of particles has a mass density
\(\rho = \left\{ {\matrix{ {{\rho _0}} & {for} & {r \le R} \cr 0 & {for} & {r > R} \cr } } \right.\)
Where \(\rho_0\) is a constant. A test mass can u...

An ideal gas is expanding such that PT\(^2\) = constant. The coefficient of volume expansion of the gas is

Two balls, having linear momenta \({\overrightarrow p _1} = p\widehat i\) and \({\overrightarrow p _2} = - p\widehat i\), undergo a collision in free space. There is no external force acting on the balls. Let \({\overrightarrow {p'} _1}\) ...

If collision between the block and the incline is completely elastic, then the vertical (upward) component of the velocity of the block at point B, immediately after it strikes the second incline is

The speed of the block at point B immediately after it strikes the second incline is

The speed of the block at point C, immediately before it leaves the second incline is

A particle of mass m and charge q, moving with velocity v enters Region II normal to the boundary as shown in the figure. Region II has a uniform magnetic field B perpendicular to the plane of the paper. The length of the Region II is \(l\)...

Two cylinders, one hollow (metal) and the other solid (wood) with the same mass and identical dimensions are simultaneously allowed to roll without slipping down an inclined plane from the same height. The hollow cylinder wi...

Student I, II and III perform an experiment for measuring the acceleration due to gravity (g) using a
simple pendulum. They use different length of the pendulum and/or record time for different number
of oscillations. The observations area ...

In a Young's double slit experiment, the separation between the two slits is d and the wavelength of the light is \(\lambda\). The intensity of light falling on slit 1 is four times the intensity of light falling on slit 2. Choose the corre...
