Question

A wire having mass $m$ and length $l$ can freely slide on a pair or parallel smooth horizontal rails placed in vertical magnetic field $B$ . The rails are connected by a capacitor of capacitance $C$ . The electric resistance of the rails and the wire is zero. If a constant force $F$ acts on the wire as shown in the figure. Then, the acceleration of the wire can be given as

A

a = $\frac{C^2B^2l - F}{m}$

B

a = $\frac{F}{m + CBl}$

C

a = $\frac{FC^2B^2l}{m}$

D

a = $\frac{F}{m + C^2B^2l}$

Accepted Answer

a = $ \frac{F}{m + C^2B^2l} $

Answer

a = $ \frac{C^2B^2l - F}{m} $

Answer

a = $ \frac{F}{m + CBl} $

Answer

a = $ \frac{FC^2B^2l}{m} $
