Question A wire, carrying a current \( i \), is kept in the \( \mathrm{XY}- \) plane along the curve \( y=A \sin \left(\frac{2 \pi}{\lambda} x\right) \). A magnetic field \( B \) exists in the z-direction. The magnitude of the magnetic force on the portion of the wire between \( x=0 \) and \( x=\lambda \) is
(A) i \( \lambda \mathrm{B} \)
(B) \( 1 / 2 \mathrm{i} \lambda \mathrm{B} \)
(C) \( 2 \mathrm{i} \lambda \mathrm{B} \)
(D) \( 3 \mathrm{i} \lambda \mathrm{B} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
