0Figure shows a conducting Rectangular loop of electrical resistance \( R \). There exists a uniform magnetic field given by \( \vec{B}=B_{0}\left(10 t^{2}-5 t\right) \hat{k} \) in the region. The current in the loop at
\( \mathrm{P} \)
(1) \( t=0 \) is zero
(2) \( t=0 \) is \( \frac{10 B_{0}}{R} A \) to \( B \)
(3) \( t=\frac{1}{4} s \) is zero
(4) \( t=1 \mathrm{~s} \) is \( \frac{30 B_{0}}{R} B \) to \( A \)
