A 2.0 m long rod has a density describedby λ = a+ bx, whereλ is the density in kilograms permeter of length,a = 5.0 kg/m, b =4.0kg/m2, and x isthe distance in meters from theleft end of the rod. The rod restshorizontally with its ends eachsupported by a scale. What do thetwo scales read?
right scale
1 N
left scale
2 N
