# A ball with radius r=0.22m is submerged in syrup at a depth of 4m. What is the total force from pressure acting on the ball? ρs=1370kg/m3?

force = pressure * area

F = ρgh * 4πr²

F = 1370 * 9.8 * 4 * 4π * 0.22² N = 3.3e4 N

due to the syrup alone.

If you need to consider the atmospheric pressure as well, then

F = (1e5Pa + ρgh) * 4πr²

Of course, the NET force is zero because these forces act symmetrically.

Sorry, my answer is "Anonymous" as your post is Anonymous. There is no need for an Anonymous question in this category, Most 'Anonymous' posts are trolls, maybe yours is not, but the high likelihood is there. If you post as yourself, I would be glad to help you with any problem you have.

I spend a lot of time on each problem, I just want to make sure it's for a worthwhile cause.

There is no force from pressure acting on the ball under these conditions.
