A straight conductor is carrying a current of 2 A in +x direction along it. A uniform magnetic field \(\vec{B}=(0.6 \hat{j}+0.8 \hat{k}) T\) is switched on, in the region. The force acting on 10 cm length of the conductor is:
- \((0 \cdot 12 \hat{{j}}-0 \cdot 16 \hat{{k}}) {N}\)
- \((-0 \cdot 16 \hat{{j}}+0 \cdot 12 \hat{{k}}) {N}\)
- \((-0 \cdot 12 \hat{{j}}+0 \cdot 16 \hat{{k}}) {N}\)
- \((0 \cdot 16 \hat{j}-0 \cdot 12 \hat{k}) {N}\)
Answer
(B) (-0 16 j +0 12 k ) N
