Two vertical rails are connected at the ends with a capacitor. There is a magnetic field `vecB` directed horizontally. A wire of mass 'm' slides down the rails. Find the acceleration of wire given that mass `'m'=1kg`, `g=10ms^(-2)`, `B=1T` length of wire `=1m` capacitance `C=1` farad. (The wire and the rails offer zero electrical resistacne)

Options

A. `4ms^(-2)`
B. `6ms^(-2)`
C. `5ms^(-2)`
D. `7ms^(-2)`

Answer

C
