Answer:
Step-by-step explanation:
Given:
Gravity of Mars = 0.38 times the gravity at Earth
Gravity of Earth is,
Radius of Mars (R) = 3400 km
Mass of mars (M) = ?
We know that, the acceleration due to gravity of a planet of mass 'M' and radius 'R' is given as:
Now, as per question:
Plug in 9.8 for
and solve for
. This gives,
Now, plug in this value in the above equation and solve for 'M'. This gives,
Therefore, the mass of Mars is
.
