The ratio of masses of two planets is $2 : 3$ and the ratio of their radii are $4 : 7$ . Find the ratio of their accelerations due to gravity.

Ratio of masses of two planets (

$m_1:m_2$ )

$=$ :

Ratio of radius of two planets (

$r_1:r_2$ )

$=$ :

The formula is

$g = \frac{i \times i}{i^{i}}$

On substituting the known data and rearranging the above equation we get,

$Ratio\ of\ accelerations\ due\ to\ gravity$ (

$g_1:g_2$ )

$=$ :
