263921 An electron is travelling with velocity \(\vec{v}=3 \hat{i}+5 \hat{j} \mathrm{~m}\) s in a magnetic field \(\vec{B}=6 \hat{i}+4 \hat{j}\) tesla. Then is the magnitude and direction of the force \(\vec{F}\) acting on the electron:

1 18 e N along + ve \(z\)-axis
2 18 e N along-ve \(z\)-axis
3 \(36 \mathrm{e} N\) along-ve \(z\)-axis

263923 A coil of resistance \(400 \Omega\) is placed in a magnetic field. If the magnetic flux \(\phi\) (wb) linked with the coil varies with time \(t\) (sec) as \(\phi=50 \mathrm{t}^2+4\), the current in the coil at \(\mathbf{t}=\mathbf{2} \mathrm{sec}\) is:

1 2 A
2 1 A
3 0.5 A

263924 A conducting circular loop is placed in a uniform magnetic field, \(B=0.025 \mathrm{~T}\) with plane perpendicular to the field. The radius of the loop is made to shrink at a constant rate of \(1 \mathrm{~mm} \mathrm{~s}^{-1}\). The induced emf when the radius is 2 cm , is:

1 \(2 \pi \mathrm{WV}\)
2 \(\pi \mu V\)
3 \(\pi / 2 \mu \mathrm{~V}\)
4 \(2 \mu \mathrm{~V}\)
