5. Two forces, \(\mathbf { F } _ { 1 }\) and \(\mathbf { F } _ { 2 }\), act on a particle \(A\).
\(\mathbf { F } _ { 1 } = ( 2 \mathbf { i } - 3 \mathbf { j } ) \mathrm { N }\) and \(\mathbf { F } _ { 2 } = ( p \mathbf { i } + q \mathbf { j } ) \mathrm { N }\), where \(p\) and \(q\) are constants.
Given that the resultant of \(\mathbf { F } _ { 1 }\) and \(\mathbf { F } _ { 2 }\) is parallel to ( \(\mathbf { i } + 2 \mathbf { j }\) ),

1. show that \(2 p - q + 7 = 0\) Given that \(q = 11\) and that the mass of \(A\) is 2 kg , and that \(\mathbf { F } _ { 1 }\) and \(\mathbf { F } _ { 2 }\) are the only forces acting on \(A\),
2. find the magnitude of the acceleration of \(A\).
