When a solid object is totally submerged in a liquid on Earth, it experiences an upthrust $U_E$. The same object, when totally submerged in the same liquid on Mars, experiences an upthrust $U_M$. The acceleration of free fall on Mars is $3.7\text{ m s}^{-2}$. Assume that the density of the liquid and the object’s volume have identical values on Earth and Mars. What is the ratio $\frac{U_M}{U_E}$?
- A0.38
