In a complexometric titration of metal ion with ligand $M ($ Metal ion $)+ L ($ Ligand $) \rightarrow C ($ Complex $)$ end point is estimated spectrophotometrically (through light absorption). If 'M' and 'C' do not absorb light and only 'L' absorbs, then the titration plot between absorbed light ( $A$ ) versus volume of ligand 'L' $(V)$ would look like

An electron falls from rest through a vertical distance $h$ in a uniform and vertically upward directed electric field $E$. The direction of electrio field is now reversed, keeping its magnitude the same. A proton is allowed to fall from rest in it through the same vertical distance $h$. The time of fall of the electron, in comparison to the time of fall of the proton is
