1.	Water rises to a height of 20 mm in a capillary .If the radius of the capillary is made (1)/(3) rd of its previous is made then what is the new value of the capillary rise ?
Answer» SOLUTION :`{:(" "hprop(1)/(R),""H.=h(R)/(R.)=((R)/((R)/(3)))),(THEREFORE(h)/(h)=(R)/(R),"" h.=3h):}` `=3(20)=60mm`
