Question

Calculate the escape speed on the surface of aplanet of mass 7.5×10^25 gram, its radius 1.6×10^6m and G=6.67×10^-8 dyne cmsq. g^-2

Answer 1

mass = M = 7.34×10^22 kgradius = R = 1×10^6mG = gravitational constant = 6.67Nm²/kg²escape velocity = v = ?g = GM/R²___________v = √2Rgv = √2RGM/R²v ...
