A. Osmosis | I. Solvent molecules pass through semi permeable membrane towards solvent side. |
B. Reverse osmosis | II. Movement of charged colloidal particles under the influence of applied electric potential towards oppositely charged electrodes. |
C. Electro osmosis | III. Solvent molecules pass through semi permeable membrane towards solution side. |
D. Electrophoresis | IV. Dispersion medium moves in an electric field. |
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
