The length of a potentiometer wire is 'L'. A cell of e.m.f. 'E' is balanced at a length $\frac{L}{4}$ from the positive end of the wire. If the length of the original wire is increased by $\frac{L}{3}$, then using the same cell null point is obtained at

A convex lens of refractive index 1.5 has power 3D. It is placed in a liquid of refractive index 2. The new power of the lens is

Bohr model is applied to a particle of mass m and charge $q$ is moving in a plane under the influence of a transverse magnetic field (B). The energy of the charged particle in the second level will be ( h = Planck's constant)

The ratio of the wavelength of the last line of Paschen series to that of Balmer series is

A mass suspended from a vertical spring performs S.H.M. of period \(0.1\) second. The spring is unstretched at the highest point of suspension. Maximum speed of the mass is (Gravitational acceleration \(g = 10\text{ m/s}^2\))

Bohr model is applied to a particle of mass m and charge $q$ is moving in a plane under the influence of a transverse magnetic field (B). The energy of the charged particle in the second level will be ( h = Planck's constant)

The lengths of the two organ pipes open at both ends are ' $L$ ' and $(L + L_1)$. If they are sounded together, the beat frequency will be ($v = $ velocity of sound in air)}
