Question
A 20 cm long test tube (cylindrical) is inverted & pushed vertically down into the water . when the closed end is at water surface, how high has the water risen inside the tube? [p atm =10^5 N/m²]
Joshi sir comment
Let the height of water in the tube is x cm. then according to PV = constant, calculate the pressure by (20-x) cm. column
then P0 + pressure by 20 cm water = pressure by (20-x) cm. column + pressure by x cm water column
