$$\mathrm{A}\mathrm{chain}\mathrm{consisting}\mathrm{of}5\mathrm{links}\mathrm{each}\mathrm{of}$$$$\mathrm{mass}0.1\mathrm{kg}\mathrm{is}\mathrm{lifted}\mathrm{vertically}\mathrm{with}\mathrm{a}$$$$\mathrm{constant}\mathrm{acceleration}\mathrm{of}2\mathrm{m}/{\mathrm{s}}^2.\mathrm{The}$$$$\mathrm{force}\mathrm{of}\mathrm{interaction}\left(\mathrm{in}\mathrm{newton}\right)\mathrm{between}$$$$\mathrm{the}\mathrm{top}\mathrm{link}\mathrm{and}\mathrm{the}\mathrm{link}\mathrm{immediately}$$$$\mathrm{below}\mathrm{it}\mathrm{will}\mathrm{be}:$$$$\mathrm{Take}g=10\mathrm{m}/{\mathrm{s}}^2.$$

$$letforcebetweentoplinkand$$$$theoneimmediatelybelowbe\mathit{N}.$$$$ThenN-4mg=4ma$$$$\Rightarrow N=4m(g+a)=4.8newtons$$
