358474 An aeroplane having a wing space of \(35\;m\) flies due north with the speed of \(90\;m{s^{ - 1}}\), given \(B = 4 \times {10^{ - 5}}\;T\). The potential difference between the tips of the wings will be:

358475 Statement A :
An emf can be induced by moving a conductor into a magnetic field.
Statement B :
An emf can be induced by changing the magnetic field.

358476 Assertion :
When a conducting rod moves in uniform transverse magnetic field with uniform speed which is perpendicular to its length, then potential difference may be developed across its ends.
Reason :
In any conductor, free electrons are available.

358477 A rectangular loop has a sliding connector \(PQ\) of length \(l\) and resistance \(R\) ohm and it is moving with a speed \(v\) as shown. The set up is placed in a uniform magnetic field going into the the plane of the paper.

358478 A metallic rod of length \(1\;m\) held along east west direction is allowed to fall down freely. Given horizontal component of earth's magnetic field \({B_H} = 3 \times {10^{ - 5}}\;T\). The \(emf\) induced in the rod at an instant \(t=2 s\) after it is released is (Take \(g = 10\;m{s^{ - 2}}\) ).
