Question 420: Gravitation

Question

A spherical planet has a mass MP and diameter DP. A particle of mass m falling freely near the surface of this planet will experience an acceleration due to gravity, equal to

Accepted Answer

Gravitational attraction force on particle B,
$${F_g} = {{G{M_P}m} \over {{{\left( {{D_P}/2} \right)}^2}}}$$
Acceleration of particle due to gravity
$$a = {{{F_g}} \over m} = {{4G{M_P}} \over {D_P^2}}$$

Answer

$${{4G{M_P}} \over {D_P^2}}$$

Answer

$${{G{M_P}m} \over {D_P^2}}$$

Answer

$${{G{M_P}} \over {D_P^2}}$$

Answer

$${{4G{M_P}m} \over {D_P^2}}$$
