There exists a horizontal magnetic field in space of value \( B = 9 \times 10^{-4} \text{ T} \). A magnetic bar of magnetic moment \( M = 9 \times 10^3 \text{ J/T} \) is placed at an angle \( \theta_i = 60^\circ \) to the field and is free to rotate. Finally, it comes to a position parallel to the field. Work done by magnetic field on the magnetic bar will be

A metallic wire of uniform area of cross section has a resistance R, resistivity \(\rho\) and power rating P at V volts. The wire is uniformly stretched to reduce the radius to half the original radius. The values of resistance, resistivity and power rating at V volts are now denoted by R', and P' respectively. The corresponding values are correctly related as __________ . Fill in the blank with the correct answer from the options given below
