2.
A rectangular coil of length 0.12 m and width 0.1 m having
50 turns of wire is suspended vertically in a uniform
magnetic field of strength 0.2 Weber/m2. The coil carries a
current of 2A. If the plane of the coil is inclined at an angle
of 300 with the direction of the field, the torque required to
keep the coil in stable equilibrium will be

If two streams of protons move parallel to each other in the
same direction, then they
For charge particles, if they are moving freely in space,
electrostatic force is dominant over magnetic force
between them. Hence due to electric force they repel
each other.

A current carrying straight wire is kept along the axis of a
circular loop carrying a current. The straight wire
