Two parallel long smooth conducting rails separated by a distance l=10 cm are connected by a movable conducting connector of mass m=4mg.Terminals of the rails are connected by the resistor R=2Omega & the capacitor C=1muF as shown.A uniform magnetic field B=20T perpendicular to the plane of the rails is swiched on.The connector is dragged by a constant force F=10N.The speed of the connector as function of time if the force F is applied at t=0 is equal to v-5(1-e^(-x xx 10^(4) xx t)m//s).Find the value of x.
