Question

The force on the bottom of a tank is 120 kg wt .If the pressure is 12 Pascal ,find the area .

Answer 1

Given :-

• Force = 120 kg wt = 120 × 9.8 = 1176 N
• Pressure = 12 pascal

To find :-

• Area = ?

Solution :-

As we know,

• $\sf{Pressure~=~\dfrac{Force}{Area}}$

So,

• $\sf{Area = \dfrac{Pressure}{Force}}$

Put the given values :-

$\implies$ $\sf\dfrac{1176}{12}$

$\implies$ 98 $\sf{m^2}$

• Area = 98 $\sf{m^2}$

Thrust :-

• A force acting normally on a surface is called Thrust.
• Its S.I. unit is newton (N).
• Its CGS unit is dynes.
• It is a vector quantity.

Pressure :-

• The force acting normally on unit surface is called pressure.
• Its S.I. unit is pascal (Pa).
• It is a scalar quantity.
