Explanation:
See the attached file for the masses distributions
The force between two masses at distance r is expressed as
since the masses are of the same value, the above formula can be reduce to
using vector notation,Let use consider the force on the lower left corner of the mass due to the upper left side of the mass is
The force on the lower left corner of the mass due to the lower right side of the mass is
The force on the lower left corner of the mass due to the upper right side of the mass is
The net force can be express as
if we insert values we arrive at
if we solve for the magnitude, we arrive at
Hence the net force on one of the masses is
Answer:
The value is
Explanation:
From the question we are told that
The volume of the bottle is
The gauge pressure of the air is
Generally the volume of air before the bottle is turned upside down is
Generally the volume air when the bottle is turned upside-down is
From the the mathematical relation of adiabatic process we have that
Here r is a constant with a value r = 1.4
So
