A planet in a distant solar system is 10 times more massive than the earth and its radius is 10 times smaller. Given that the escape velocity from the earth is $11 \mathrm{~kms} ^ { - 1 }$, the escape velocity from the surface of the planet would be
(1) $1.1 \mathrm{~kms} ^ { - 1 }$
(2) $11 \mathrm{~kms} ^ { - 1 }$
(3) $110 \mathrm{~kms} ^ { - 1 }$
(4) $0.11 \mathrm{~kms} ^ { - 1 }$
