The largest and the shortest distance of the earth from the sun are \[{{r}_{1}}\] and \[{{r}_{2}}\], its distance from the sun when it is at the perpendicular to the major axis of the orbit drawn from the sun [CBSE PMT 1991]

\[\frac{{{r}_{1}}+{{r}_{2}}}{3}\]

\[\frac{{{r}_{1}}+{{r}_{2}}}{4}\]

\[\frac{{{r}_{1}}{{r}_{2}}}{{{r}_{1}}+{{r}_{2}}}\]

\[\frac{2{{r}_{1}}{{r}_{2}}}{{{r}_{1}}+{{r}_{2}}}\]
