(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A particle in circular orbit moves in a force field given by F(r)=-k/r^2. If k is halved what will the new orbit be?

2. Relevant equations

The answer is the orbit becomes parabolic but how? how does the total energy become zero as for parabolic orbits total energy=0? help please
