Question

This table shows the acceleration due to gravity on four planets. PlanetGravity (m/s2) Earth9.8 Mercury3.7 Neptune11.2 Uranus8.9 A person would have a different weight on each planet. Arrange the planets in increasing order based on a person’s weight on the planet. Mercury Neptune Earth Uranus < <

Answer 1

Given values of acceleration due to gravity on each planets as,

1, Acceleration due to gravity on Earth,

$g_e=9.8ms^{-1}$

2, Acceleration due to gravity on Mercury,

$g_m=3.7ms^{-1}$

3, Acceleration due to gravity on Neptune,

$g_n=11.2ms^{-1}$

4, Acceleration due to gravity on Uranus,

$g_u=8.9ms^{-1}$

The weight of the body on any planet is defined as,

$W=mg$

which shows that weight is directly propotional to the acceleration due to gravity on that planet.

As, the order of the acceleration due to gravity is,

$g_n>g_e>g_u>g_m_{}$

Thus, the increasing order of the weight of the body on the planet is,

$undefined$
