A long straight wire carries a constant current of 5 Amp. At a distance of 10 cm from the straight wire, a small straight conductor of length 10 cm is placed parallel to the wire and carries a current of 3 amp having mass 3 gm. If it is released from its position, the acceleration of the conductor just after being released is
- \(10^{-3} \mathrm{~m} / \mathrm{s}^{2}\)
- \(2 \times 10^{-3} \mathrm{~m} / \mathrm{s}^{2}\)
- \(4 \times 10^{-3} \mathrm{~m} / \mathrm{s}^{2}\)
- \(5 \times 10^{-3} \mathrm{~m} / \mathrm{s}^{2}\)
Answer
(B) 2 10^ -3 ~m / s ^ 2
