Question

Relative density of a body on the surface of Earth is given by $R_1$ and the relative density of the same body on moon is given by $R_2$. What will be the relation between $R_1$ and $R_2$.

• A.
  $R_1$ = $R_2$
• B.
  $R_1$ = $R_2-9.8$
• C.
  $R_1$ = $R_2+1.62$
• D.
  $R_1=\frac{R_2}{6}$

Answer 1

The correct option is A

$R_1$ = $R_2$
$R_1$ = $R_2$
Relative density of a body depends on the mass and volume of the body, both of which remain unaffected by the gravity of the Earth. Since, gravity does not play a role here, relative density of the body remains constant everywhere.
