369828 A toy cart is tied to the end of an unstretched string of length \(l\). When revolved, the toy cart moves in horizontal circle with radius \(2 l\) and time period \(T\). If it is speeded until it moves in horizontal circle of radius \(3 l\) with period \(T_{1}\), relation between \(T\) and \(T_{1}\) is (Hooke's law is obeyed)

369829 The young's modulus of brass and steel are respectively \(1.0 \times {10^{10}}\;N/{m^2}\) and \(2 \times {10^{10}}\;N/{m^2}\). A brass wire and a steel wire of the same length are extended by \(1\;mm\) under the same force, the radii of brass and steel wires are \(R_{B}\) and \(R_{S}\) respectively. Then
