\end{figure} A particle \(Q\) of mass 5 kg is attached by two light inextensible strings to two fixed points \(A\) and \(B\) on a vertical pole. Each string has length 0.6 m and \(A\) is 0.4 m vertically above \(B\), as shown in Figure 1. Both strings are taut and \(Q\) is moving in a horizontal circle with constant angular speed \(10 \mathrm { rad } \mathrm { s } ^ { - 1 }\). Find the tension in
  1. \(A Q\),
  2. \(B Q\).
