Question

A liquid of mass 1 kg is filled in a flask as shown in figure. The force exerted by the flask on the liquid is (g = 10 m/s)[Neglect atmospheric pressure): (A) 10 N (B) greater than 10N (C) less than 10N (D) zero dienolarea - 1cm2 It is filled w​

Answer 1

Answer:

A 10 N

Explanation:

because every action has opposite and equal reaction

Answer 2

The force exerted by the liquid on the flask  is 10 N.

(A) is correct option.

Explanation:

Given that,

Mass of liquid = 1 kg

There is no atmospheric pressure and liquid is stationary with respect to flask  .

We need to calculate the force exerted by the liquid on the flask

Using balance equation

$F_{y}+\rho gh=mg$

$F_{y}=mg$

Put the value into the formula

$F_{y}=1\times10$

$F_{y}=10\ N$

Hence, The force exerted by the liquid on the flask  is 10 N.
