Question

Suppose that in a parallel universe gravity were as strong as the electrical force. That is, suppose that the

gravitational constant had the value G=9.0 times 10^{9};{rm N cdot m^{2}/kg^{2}}, instead of the value it has in our universe. In terms of the present year (the 365 days it takes for the earth to go around the sun), how long would the earth's year be in this parallel universe, assuming that the sun had the same mass that it presently does and that the earth moved in a circular orbit having the same radius as its present orbit?
