Question
A straight wire is carrying an electric current.
- there are no magnetic liens of force near the wire
- there are lines of force and they are circular lines encircling the wire
- the liens of force are straight lines parallel to the wire and in the direction opposite to the current
- the liens of force are straight lines parallel to the wire in the direction opposite the current
The correct answer is: there are lines of force and they are circular lines encircling the wire

A uniform thin rod of mass M and length L is standing vertically along the Y–axis on a smooth horizontal surface with its lower end at origin (0, 0). A slight disturbance at t = 0 causes the lower end to slip on smooth surface along the positive X–axis and the rod starts falling. The path followed by the centre of mass of the rod during its fall is a/an.
