    How Does the Decreasing Mass of the Sun Affect Earth's Orbital Radius?

    1. The mass of the sun is decreasing as dM/dt=-constant .M Find [dr/dt]/r for the earth Homework Equations [b]3. I tried using M=M0-alpha. t and then separating the variables in the equation GMm/r^2=mdv/dt. I don't knot the right way to solve this. Plz tell me how to solve this...
