a straight rod has one end at the origin and the other end at the point (l,0) and a linear density given by λ=ax2, where a is a known constant and x is the x coordinate. since this wire is not uniform, you will have to use integration to solve this part. use m=∫l0dm to find the total mass m. find xcm for this rod.

The difference between the observed value and the mean of the set of values is a
