Hello.
00:03
So it is given to us in the question that the mass of the cannon bowl is 5 kilograms.
00:08
The pressure p1 on one side of the cannon bolt is 7 megapascal and the diameter d is equal to 0 .15 meter.
00:19
Okay.
00:20
Now the 7 megapascal can be written as 7 ,000 kilo pascal.
00:26
Okay.
00:28
7 ,000 kilo pascal.
00:31
Okay, now we know that the atmospheric pressure p0 is equal to 101 kilo pascal.
00:45
Okay, now this canon board is in contact with the atmosphere on one end, which has a pressure of p0 is equal to 101 kilopascal and is in contact with the gunpowder on the other end, which produces.
01:02
A 7 ,000 kilo -pascal of pressure when it burns.
01:06
Okay, thus we can write the force is equal to force f is equal to p1 minus p0 multiplied by area of cross -section.
01:25
Okay, now what is area of cross -section? area of cross -section a will be equal to pi multiplied by r.
01:35
Square but we are given the diameter here this we can write pi multiplied by d divided by two the whole square which is equal to pi d square divided by four okay now substituting this in the equation of force we get f is equal to p1 minus p2 multiplied by pi d square divided by 4...
