A force $\left(\overrightarrow{\mathrm{F}}\right)=3\widehat{\mathrm{i}}+\mathrm{c}\widehat{\mathrm{j}}+2\widehat{\mathrm{k}}$  acting on a particle causes a displacement: $\left(\overrightarrow{\mathrm{s}}\right)=-4\widehat{\mathrm{i}}+2\widehat{\mathrm{j}}+3\widehat{\mathrm{k}}$  in its own direction. If the work done is 6 J, then the value of ‘c’ is
