When a part of a straight capillary tube is placed vertically in a liquid, the liquid raises upto certain height $\displaystyle h$. If the inner radius of the capillary tube, density of the liquid and surface tension of the liquid decrease by $\displaystyle 1 \%$ each, then the height of the liquid in the tube will change by $\displaystyle \_\_\_\_$ %.
