(N/A) Soil contains fine capillary tubes formed by the arrangement of soil particles. Through these capillaries,water from the deeper layers rises to the surface due to capillary action and evaporates,causing the soil to dry out. When a farm is ploughed,these capillary tubes are broken. This disruption prevents the water from rising to the surface,thereby retaining moisture in the soil.

$A$ glass capillary tube of inner diameter $0.28 \,mm$ is lowered vertically into water in a vessel. The pressure to be applied on the water in the capillary tube so that the water level in the tube is the same as that in the vessel is ............ $\times 10^3 \,N/m^2$ (surface tension of water $= 0.07 \,N/m$ and atmospheric pressure $= 10^5 \,N/m^2$).
