1.	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 perpendicular to the major-axis of the orbit drawn from the sun is:
Answer» `(r_(1) + r_(2))/4` `(r_(1) + r_(2))/(r_(1)-r_(2))` `(2r_(1)r_(2))/(r_(1) + r_(2))` `(r_(1) + r_(2))/3` ANSWER :C
