In this problem, we have been given that there is a ball, and this ball is completely submerged underwater, and the mass of the ball, well, that's given as 15 kilograms, and it has volume of 0 .2 cubic meters, and we are required to determine the net force which is experienced by this ball underwater.
00:27
So we are also given the density of water as 10 raised to 3 kilograms per cubic meter, which we will be using, and the acceleration due to gravity, that is given as 10 meters per second square.
00:40
So if you look at the free body diagram, there will be weight of this ball, which is in the vertically downward direction because of gravity, and that can be computed by using this equation.
00:51
So when we put the values here, we get the weight as mass into acceleration due to gravity, that's 150 newtons.

And there will be upward force according to archimede's principle and we will use this equation to get the upward force that's called as upthrust and this is row times v.
