What happens to the balanced-growth-path values of capital per worker, output per worker, and consumption per worker

Consider a Solow economy that is on its balanced growth path.  Assume for simplicity that there is no technological progress.  Now suppose that the rate of population growth falls.

a. What happens to the balanced-growth-path values of capital per worker, output per worker, and consumption per worker? Sketch the paths of these variables as the economy moves to its new balanced growth path.

b. Describe the effect of the fall in population growth on the path of output (that is, total output, not output per worker)
