Re: finding centre of mass of a semicircular lamina
Yaa.. that's what I am trying to figure out.. the density function.. and after that its pretty straight forward.
Suppose the density of any point on a semicircular lamina {(x, y) : x >= 0,$$ x^2 + y^2$$ <= r^2 is proportional to its distance from the origin. Compute the centre of mass.
I am trying to figure out what is the density function for this case.
