The maximum and minimum distances of comet from the Sun are 1.6 × 1012 m and 8.0 × 1010 m respectively

The maximum and minimum distances of comet from the Sun are 1.6 × 10¹² m and 8.0 × 10¹⁰ m respectively If the speed of the comet at the nearest point is 6 × 10⁴ ms^–1, the speed at the farthest point is :

(1) 3.0 × 10³ m/s (2) 4.5 × 10³ m/s (3) 1.5 × 10³ m/s (4) 6.0 × 10³ m/s

Best answer

The correct answer is option A) 3.0×10³ m/s

Explanation::

\(L=mv_1r_1=mv_2r_2\)

\(V_2={ v_1r_1\over r_2}\)

\(=v_1{ 8×10^{10}\over 160×10^{10}}\)

\(={6×10^4\over 20}\)

\(=3000 m/s\)
