So here it is given that ear damage from divining if the force on the tympanic membranes, that is ear drum, increased by the 1 .5 newton.
00:14
Above the force from the atmospheric pressure, the membranes can be damaged.
00:19
Now, when you go, the kuba diving in the ocean below water depth could damage to your ear drum start to occur, while ear drum is typically of 8 .2 millimeter in diameter.
00:40
So as it is asked to find at what depth could damage the ear drum start to occur.
00:48
So for this, the ear drum is typically of 8 .2 millimeter in diameter.
00:56
So therefore the pressure or we can say the total pressure, at the eardrum will be p equals to p .0 plus row gh, where h is indicating the depth of damage or the depth of ear drum.
01:18
Now as we know that the pressure p is nothing but equals to the force upon area.
01:26
So from here we can say that the force divided by area.
01:32
This should be equals to p minus p nod, that is difference to the total pressure minus initial pressure and this should be equal to the row g h here...
