Let I1 and I2 be the steady currents passing through a long horizonta

1.	Let I1 and I2 be the steady currents passing through a long horizontal wire XY and PQ respectively. The wire PQ is fixed in horizontal plane and the wire XY be is allowed to move freely in a vertical plane. Let the wire XY is in equilibrium at a height d over the parallel wire PQ as shown in figure.
Answer» If the wire XY is slightly displaced and released, it executes simple uarmonic motion due to force of repulsion produced between the current carrying wire. Acceleration of the wire, a = -ω²y Time period of oscillation of the wire, T = 2π\(\sqrt{\frac{d}{g}}\)

Answer»

If the wire XY is slightly displaced and released, it executes simple uarmonic motion due to force of repulsion produced between the current carrying wire.

Acceleration of the wire, a = -ω²y

Time period of oscillation of the wire,

T = 2π\(\sqrt{\frac{d}{g}}\)
