A thin rod of length 1 m is fixed in a vertical position inside a train, which is moving horizontally with constant acceleration\[4m/{{s}^{2}}\]. A bead can slide on the rod, and friction coefficient between them is\[\frac{1}{2}\]. If the bead is released from rest at the top of the rod. The time when it will reach at the bottom. \[\left[ g=10m/{{s}^{2}} \right]\]is t, then value of\[\frac{1}{t}\].
