Question

An object is thrown from the surface of the moon. The escape speed for the object is

• A. $\sqrt{2 g^{\prime} R_{m}}$, where $g^{\prime}=$ acceleration due to gravity on the moon and $R_{m}=$ radius of the moon
• B. $\sqrt{2 g^{\prime} R_{E}}$, where $g^{\prime}=$ acceleration due to gravity on the moon and $R_{E}=$ radius of the earth
• C. $\sqrt{2 g R_{m}}$, where $g=$ acceleration due to gravity on the earth and $R_{m}=$ radius of the moon
• D. None of the above

Answer 1

Answer: (A)

Correct answer is (a) $\sqrt{2 g^{\prime} R_{m}}$, where $g^{\prime}=$ acceleration due to gravity on the moon and $R_{m}=$ radius of the moon
