Calculate the pressure exerted on a surface of 0.5 m2 by a thrust of 100 kgf.
उत्तर
Given:
Thrust (F) = 100 kgf
Area = 0.5 m2
Pressure = ?
Pressure = `"Thrust "/"Area"`
= `100/0.5`
=`1000/5`
Pressure = 200 kgf m−2

Two vessels have the same base area but different shapes. The first vessel takes twice the volume of water that the second vessel requires to fill up to a particular common height. Is the force exerted by the water on the base of the vessel the same in the two cases? If so, why do the vessels filled with water to that same height give different readings on a weighing scale?
