A 1 cm segment of a wire lying along x -axis carries current of 0.5 A along \(+x\) direction. A magnetic field \(\vec{B}=(0.4 {mT}) \hat{j}+(0.6 {mT}) \hat{k}\) is switched on, in the region. The force acting on the segment is
- \((2 \hat{{j}}+3 \hat{{k}}) {mN}\)
- \((-3 \hat{j}+2 \hat{k}) \mu {N}\)
- \((6 \hat{{j}}+4 \hat{{k}}) {mN}\)
- \((-4 \hat{{j}}+6 \hat{{k}}) \mu {N}\)
Answer
(B) (-3 j +2 k ) N
