A charge $ Q $ is divided into two charges $ q $ and $ Q-q $ . The value of $ q $ such that the force between them is maximum, is

In a double slit interference experiment, the fringe width obtained with a light of wavelength $ 5900\, ??$ was $ 1.2\,mm $ for parallel narrow slits placed $ 2\,mm $ apart. In this arrangement, if the slit separation is increased by one-and-half times the previous value, then the fringe width is

An electrically charged particle enters into a uniform magnetic induction field in a direction perpendicular to the field with a velocity $ v $ . Then, it travels

At a certain place, the angle of dip is $ 60^{\circ} $ and the horizontal component of the earth?? magnetic field $ (B_{H}) $ is $ 0.8 \times 10^{-4} \, T $ . The earth?? overall magnetic field is

In the circuit shown, the heat produced in $ 5\,\Omega $ resistance due to current through is $ 50 \,J/s $ . Then, the heat generated per second in $ 2\,\Omega $ resistance is

A steady current flows in a long wire. It is bent into a circular loop of one turn and the magnetic field at the centre of the coil is $ B $ . If the same wire is bent into a circular loop of $ n $ turns, the magnetic field at the centre of the coil is

Two concentric hollow spherical shells have radii $ r $ and $ R \left(R\,>>\,r\right) $ . A charge $ Q $ is distributed on them such that the surface charge densities are equal. The electric potential at the centre is
