The escape velocity of body from the earth is 11.2 km s−111.2 \mathrm {~km} \mathrm {~s} ^ { - 1 } Ignoring air resistance, the escape velocity of 10 kg of the iron ball from the earth will be

A

0.0112 km s−10.0112 \mathrm {~km} \mathrm {~s} ^ { - 1 }

B

0.112 km s−10.112 \mathrm {~km} \mathrm {~s} ^ { - 1 }

C

11.2 km s−111.2 \mathrm {~km} \mathrm {~s} ^ { - 1 }

D

0.56 km s−10.56 \mathrm {~km} \mathrm {~s} ^ { - 1 }

Answer

11.2 km s−111.2 \mathrm {~km} \mathrm {~s} ^ { - 1 }

Explanation

Solution

The escape velocity is independent of the mass of the body.
