Five forces \[{{\vec{F}}_{1}},{{\vec{F}}_{2}},{{\vec{F}}_{3,}}{{\vec{F}}_{4}},\,and\,{{\vec{F}}_{5}}\] are acting on a particle of mass 2.0 kg so that it is moving with \[4\,m/{{S}^{2}}\] in east direction. If \[{{\vec{F}}_{1}}\]  force is removed, then the acceleration becomes \[7\,m/{{S}^{2}}\] in north, then the acceleration of the block if only \[{{\vec{F}}_{1}}\] is acting will be \[\sqrt{N}\,m/{{s}^{2}}\]. Find the value of n.
