Question

Assertion : Basic difference between an electric line and
magnetic line of force is that former is discontinuous and
the later is continuous or endless.
Reason: No electric lines of force exist inside a charged
body but magnetic lines do exist inside a magnet. |
Assertion : A small coil carrying current, in equilibrium, is
perpendicular to the direction of the uniform magnetic field.
Reason: Torque is maximum when plane of coil and direction
of the magnetic field are parallel to each other,
Assertion : A proton moves horizontally towards a vertical
long conductor having an upward electric current. It will
deflect vertically downward.
Reason: Seeing the proton and the conductor from the
side of the proton, the magnetic field at the site of the proton
will be towards right. Hence the force F-qu x B will deflect
the proton vertically downward.
Assertion : An induced e.m.f. appears in any coil in which
the current is changing.
Reason: Selfinduction phenomenon obeys Faraday's law
of induction.
Assertion: U nucleus, by absorbing a slow neutron
undergoes nuclear fission with the evolution of a significant
quantity of heat
Reason: During nuclear tission a part ofthe original mass
of Us is lost and gets converted into heat
