Two planets have the same average density but their radii are $${{R}_{1}}$$ and $${{R}_{2}}$$. If acceleration due to gravity on these planets be $${{g}_{1}}$$ and $${{g}_{2}}$$ respectively, then [AIIMS 1985]

Question

TuteeHUB · Accepted Answer

$$\frac{{{g}_{1}}}{{{g}_{2}}}=\frac{{{R}_{2}}}{{{R}_{1}}}$$

TuteeHUB · Answer

$$\frac{{{g}_{1}}}{{{g}_{2}}}=\frac{{{R}_{1}}}{{{R}_{2}}}$$

TuteeHUB · Answer

If assertion is true but reason is false.

TuteeHUB · Answer

$$\frac{{{g}_{1}}}{{{g}_{2}}}=\frac{R_{1}^{3}}{R_{2}^{3}}$$

1.	Two planets have the same average density but their radii are \[{{R}_{1}}\] and \[{{R}_{2}}\]. If acceleration due to gravity on these planets be \[{{g}_{1}}\] and \[{{g}_{2}}\] respectively, then [AIIMS 1985]
A.	\[\frac{{{g}_{1}}}{{{g}_{2}}}=\frac{{{R}_{1}}}{{{R}_{2}}}\]
B.	\[\frac{{{g}_{1}}}{{{g}_{2}}}=\frac{{{R}_{2}}}{{{R}_{1}}}\]
C.	If assertion is true but reason is false.
D.	\[\frac{{{g}_{1}}}{{{g}_{2}}}=\frac{R_{1}^{3}}{R_{2}^{3}}\]
Answer» B. \[\frac{{{g}_{1}}}{{{g}_{2}}}=\frac{{{R}_{2}}}{{{R}_{1}}}\]
