Question

An object is thrown from the surface of the moon. The escape speed for the object is (A) √2 g prime Rm, where g prime= acceleration due to gravity on the moon and Rm= radius of the moon (B) √2 g prime RE, where g prime= acceleration due to gravity on the moon and RE= radius of the earth (C) √2 g Rm, where g= acceleration due to gravity on the earth and Rm= radius of the moon (D) None of the above

Tardigrade Admin · Accepted Answer

Correct answer is (a) √2 g prime Rm, where g prime= acceleration due to gravity on the moon and Rm= radius of the moon

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

$2 g^{'} R_{m}$ , where $g^{'} =$ acceleration due to gravity on the moon and $R_{m} =$ radius of the moon

$2 g^{'} R_{E}$ , where $g^{'} =$ acceleration due to gravity on the moon and $R_{E} =$ radius of the earth

$2 g R_{m}$ , where $g =$ acceleration due to gravity on the earth and $R_{m} =$ radius of the moon

None of the above

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

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

2g′Rm​​, where g′= acceleration due to gravity on the moon and Rm​= radius of the moon

2g′RE​​, where g′= acceleration due to gravity on the moon and RE​= radius of the earth

2gRm​​, where g= acceleration due to gravity on the earth and Rm​= radius of the moon

None of the above

Correct answer is (a) 2g′Rm​​, where g′= acceleration due to gravity on the moon and Rm​= radius of the moon

$2 g^{'} R_{m}$ , where $g^{'} =$ acceleration due to gravity on the moon and $R_{m} =$ radius of the moon

$2 g^{'} R_{E}$ , where $g^{'} =$ acceleration due to gravity on the moon and $R_{E} =$ radius of the earth

$2 g R_{m}$ , where $g =$ acceleration due to gravity on the earth and $R_{m} =$ radius of the moon

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