   In Sun-Earth system, the distance between Lagrange points L2 and L3 is about

   1. 15 lakh kilometre
   2. 30 lakh kilometre
   3. 16 crore kilometre
   4. 32 crore kilometre

   सूर्य-पृथ्वी तंत्र में, लग्रांज बिंदुओं (Lagrange point) L2 और L3 के बीच लगभग कितनी दूरी है?

   1. 15 लाख किलोमीटर
   2. 30 लाख किलोमीटर
   3. 16 करोड़ किलोमीटर
   4. 32 करोड़ किलोमीटर
   Show answer

   Answer: (4) 32 crore kilometre

   उत्तर: (4) 32 करोड़ किलोमीटर

   L2 lies about 15 lakh km beyond the Earth on the side away from the Sun (about 15.1 crore km from the Sun), while L3 lies on the far side of the Sun at roughly the Earth-Sun distance (about 15 crore km). So L2 and L3 are about 15.1 + 15 ≈ 30 crore km apart, and the closest option is 32 crore km; 15 lakh km is only the Earth-L2 distance and 16 crore km is only about one Sun-Earth distance.
