If the mass of mars is 0.107 times that of earth, and its radius is 0.530 that of earth, estimate the gravitational acceleration g at the surface of mars. (gearth = 9.80 m/s2

To develop this problem we will use the gravitational equations posed in the Newtonian theory and for which gravity is described as,

Where,

G = Gravitational Universal constant

= Mass of mars

= Radius of mars

Using the relation given we have,

The first term is known to all as gravity on earth, which is equivalent to

Therefore the gravitational acceleration at the surface of Mars is

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
