A uniform wire of mass m and length I can freely slide on a pair of parallel, frictionless, horizontal rails placed in a vertical constant magnetic field B (as shown in figure ). The rails are connected by a capacitor of capacitance C. The electric resistance of the circuit is zero. A constant horizontal force F acts on the middle point of wire begining t = 0 ,and the wire is at rest t = 0.

At t= 0 , acceleration of wire is

A

`(F)/(m)`
