The acceleration of moon with respect to earth is 0.0027ms-2and the acceleration of an apple falling on the earth surface is about 10ms-2. Assume that the radius of the moon is one fourth of the earth’s radius. If the moon is stopped for an instant and then released, it will fall towards the earth. The initial acceleration of the moon towards the earth will be
A. 10 ms-2

B. 0.0027 ms-2

C. 6.4 ms-2

D. 5.0 ms-2

Answer :

Here, we need to know the value of acceleration due to gravity experienced by the moon. The distance between the Earth and moon is about 60 times the Earth’s radius.

Hence, the acceleration due to gravity would be,



Hence, the initial acceleration of main would be .
