The acceleration of moon with respect to earth is $0.0027 \mathrm{m} {\mathrm{s}}^{-2}$, and the acceleration of an apple falling on earth's surface is about $10 \mathrm{m} {\mathrm{s}}^{-2}$. 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

Suppose the acceleration due to gravity at the Earth's surface is $10 \mathrm{m} {\mathrm{s}}^{-2}$ and at the surface of Mars it is $4.0 \mathrm{m} {\mathrm{s}}^{-2}$. A $60 \mathrm{kg}$ passenger goes from the Earth to Mars in a spaceship moving with a constant velocity. Neglect all other objects in the sky. Which part of the given figure best represents the weight (net gravitational force of the passenger) as a function of time?

Taking the effect of bulging of earth and its rotation into account, consider the following statements:
(A) There are points outside the earth where the value of $g$ is equal to its value at the equator.
(B) There are points outside the earth where the value of $g$ is equal to its value at the poles.
