The escape velocity from the earth is about 11 km/second. The escape velocity from a planet having twice the radius and the same mean density as the earth, is
Added by George K.
Step 1
Step 1: The escape velocity formula is given by \(v = \sqrt{\frac{2GM}{R}}\), where \(v\) is the escape velocity, \(G\) is the gravitational constant, \(M\) is the mass of the planet, and \(R\) is the radius of the planet. Show more…
