Q: A uniform conducting wire $A B C$ has a mass of $10 \,g$. A current of $2 \,A$ flows through it. The wire is kept in a uniform magnetic field $B=2 T$. The acceleration of the wire will be ............. $ms ^{-2}$

b (b) Force on wire $A B C$ will be same as force on wire $A C$, using $F=i(\vec{l} \times \vec{B})$ $F=2\left(\frac{3}{100}\right)(2) \sin 90^{\circ}$ $=12 \times 10^{-2} \,N$ $a=\frac{F}{m}=\frac{12 \times 10^{-2}}{10^{-2}}=12 \,m / s ^2$
