The mass of a planet and its diameter are three times those of earth's. Then the acceleration due to gravity on the surface of the planet is ....... $m/s^2$

- A
$3.3$

- B
$4.9$

- C
$19.6$

- D
$29.4$

The height of any point $P$ above the surface of earth is equal to diameter of earth. The value of acceleration due to gravity at point $P$ will be : (Given $g=$ acceleration due to gravity at the surface of earth)

The acceleration due to gravity on a planet is $1.96 \,m / s ^2$. If it is safe to jump from a height of $3 \,m$ on the earth, the corresponding height on the planet will be ........ $m$

If the earth were to cease rotating about its own axis. The increase in the value of $g$ in $C.G.S.$ system at a place of latitude of $45^o$ will be ........ $cm/sec^{2}$.

The radii of two planets are respectively ${R_1}$ and ${R_2}$ and their densities are respectively ${\rho _1}$ and ${\rho _2}$. The ratio of the accelerations due to gravity at their surfaces is
