Question

A liquid of mass $1kg$ is filled in a flask as shown in figure.The force exerted by the flask on the liquid is $(g=10m/s^2)$ [Neglect atmospheric pressure]

• A. $10N$
• B. greater than $10N$
• C. less than $10N$
• D. zero

Answer 1

The correct option is A $10N$

Force applied by liquid on flask $=mg=1\times 10=10N$

As there is no atmospheric pressure and liquid is stationary with respect to flask

so force exerted by the liquid on flask = force exerted by flask on liquid $=10N$
