What will be the escape speed from a planet having radius thrice that of earth and the same mean density as that of the earth ? (Take `v_(e)=11.2` km/s)

What will be the escape speed from, a planet having volume 27 times that of earth and the same mean density as that of the earth? Take escape speed from the earth 11.2 km/s, earth and planet are perfectly sphere)

What will be the escape speed from, a planet having volume 27 times that of earth and the same mean density as that of the earth? Take escape speed from the earth 11.2 km/s, earth and planet are perfectly sphere)

What will be the escape speed from a planet having mass 16 times that of earth and diameter 8 times that of the earth ? (v_(e)=11.2 "kms"^(-1))

What will be the escape speed from a planet having mass 16 times that of earth and diameter 8 times that of the earth ? (v_(e)=11.2 "kms"^(-1))

What will be the escape speed from a planet having mass 8 times that of earth and diameter 4 times that of the earth ? [v_(e)=11.2 km//s]

What will be the escape speed from a planet having mass 8 times that of earth and diameter 4 times that of the earth ? [v_(e)=11.2 km//s]

What will be the escape speed from a planet having mass 8 times that of earth and diameter 4 times that of the earth ? [v_(e)=11.2 km//s]

The escape velocity from the earth is 11 km//s . The escape velocity from a planet having twice the radius and same density as that of the earth is (in km//s )
