The density of a newly discovered planet is twice that of the earth. The acceleration due to gravity at
P
the surface of the planet is equal to that at the
W
surface of the earth. If the radius of the earth is \( R \) and the radius of the planet is ' \( R_{0} \) '. Then what is the value of \( \frac{R}{R_{0}} \) ?
