Assertion : Current in wire-1 is in the direction as shown in figure. The bottom wire is fixed. To keep the upper wire stationary, current in it should be in opposite direction. Reason : Under the above condition, equilibrium of upper wire is stable.

Assertion : Zeroth law can also be termed as law of thermal equilibrium. Reason : Two objects in thermal equilibrium with the third one, are in thermal equilibrium with each other.

There are two infinite parallel current carrying wires in vertical plane. Lower wire is fixed and upper wire is having a linear mass density lambda . Two wires are carrying currents I_(1) and I_(2) . Now upper wire is placed in a magnetic field produced by lower wire. Magnetic field due to lower wire at the location of upper wire is (mu_(0)I)/(2pid) , where I_(1) current lower wire, d separation between wires. Force on any small portion of upper wire having length dl is dF=(mu_(0)I_(1)I_(2)dl)/(2pid), where I_(2) current in the upper wire. If directions of current in the wires is appropriate then upper wire can be in equilibrium if its weight is balanced by magnetic force. Now answer the following questions. Equilibrium separation between the two wires is

The force per unit length between two parallel current carrying wires = (mu_(0)i_(1)i_(2))/(2pir) . The force is attractive when the current is in same direction and repulsive, when the they are in opposite directions. The force between the wires of two parallel wires is shown. We can determine the equilibrium position. Then we displace upper wire by a small distance, keeping lower wire fixed. If the wire returns to or tries to return to its equilibrium position, its equilibrium is stable. We can thus show that upper wire can execute linear simple harmonic motion or not. The length of wire AB is large as compared to separation between the wires. If wire CD is in equilibrium position then which of the following may represent the directions of current in the wires
