The centripetal force increases with increasing radii. The mud on the edge is the farthest away ergo maximum radii. Hence it experiences greatest force and flies of first. The mud on the disc will also fly off but after the mud on the edge has flown off.I'm sorry but I don't get it
So here's what I think ... please correct me wherever possible
1. The mud is placed on the disc when the disc is stationary
2. The disc starts to move with an increasing angular velocity w (omega)
3. The centripetal force keeps the mud on the disc so it doesn't fly off
4. At the edges the centripetal force is greater than at the center
So I hope these 4 points are correct
Then the centripetal force holds the mud in place so it doesn't fly off right? ...
So if this force is greater, why will the mud fly off when it's role is to hold it in place?
