he observed M-R relation for exoplanets in the range of Jovian
masses shows that their planetary radii are virtually independent
of their masses. Considering the pressures in the interiors of
Jovian planets and that their interiors follow the pressure
relation P = ÎșÏ2 where Îș is a constant â (a) show why this result
is expected. How does R scale with Îș? (b) Calculate the value of R
if Îș=2.7 x 105 m5 kg-1 s-2 and compare with observed value for
Jupiterâs radius.
