A planet is revolving around sun in elliptical orbit. Maximum & minimum distance of planet from sun are respectively 1.6 × 1012 m and 6 × 1010 m. Find minimum speed if maximum speed of planet is 8 × 104 m/s?

(1) 3 × 104 m/s (2) 3 × 103 m/s (3) 8 × 103 m/s (4) 4 × 104 m/s

Correct answer is 3) 8$$\times 10^3 m/s$$
