A uniform horizontal rod of length 40 cm and mass 1.2 kg is supported by two identical wires as shown in figure. Where should a mass of 4.8 kg be placed on the rod so that the same tuning fork may excite the wire on left into its fundamental vibrations and that on right into its first overtone ? Take `g=10ms^-2`

A straight horizontal conducting rod of length 0*60m and mass of 60g is suspended by two vertical wires at its ends. A current of 5*0A is set up in the rod through the wire. (a) What magnetic field should be set up normal to the conductor in order that the tension in the wire is zero? (b) What will be total tension in the wires if the direction of current is reversed, keeping the magnetic field same as before (Ignore mass of the wire), g=10ms^-2 .
