3 Two particles, \(A\) and \(B\), have masses 4 kg and 6 kg respectively. They are connected by a light inextensible string that passes over a smooth fixed peg. A second light inextensible string is attached to \(A\). The other end of this string is attached to the ground directly below \(A\). The system remains at rest, as shown in the diagram.

1. 1. Write down the tension in the string connecting \(A\) and \(B\).
   2. Find the tension in the string connecting \(A\) to the ground.
2. The string connecting particle \(A\) to the ground is cut. Find the acceleration of \(A\) after the string has been cut.
