266414 The following diagram shows a wire ab of length I and resistance R sliding on a smooth pair of rails with a velocity \(v\) towards right. A uniform magnetic fireld B acts normal to the plane containing the rails and the wire inwards, S is a current source providing a constant current I in the circuit. Then, the potential difference between \(a\) and \(b\) is:

1 BvI
2 \(\mathbb{R}\)
3 \(\mathrm{Bva}-\mathrm{IR}\)
4 \(B v I+\mathbb{R}\)

266415 Two masses of 10 kg and 20 kg respectively are connected by a massless spring as shown in figure. A force of 200 N acts on the 20 kg mass. At the instant when the 10 kg mass has an acceleration of \(10 \mathrm{~ms}^{-2}\), the acceleratin of the 20 kg mass is:

1 \(2 \mathrm{~m} \mathrm{~s}^{-2}\)
2 \(5 \mathrm{~m} \mathrm{~s}^{-2}\)
3 \(10 \mathrm{~m} \mathrm{~s}^{-2}\)
4 \(20 \mathrm{~m} \mathrm{~s}^{-2}\)
