Question

A planet moving along an elliptical orbit is closest to the sun at a distance r1 and farthest away at a distance of r2. If v1 and v2 are the liner velocities at these points respectively, then the ratio v subscript 1 over v subscript 2 is

  1. r subscript 1 over r subscript 2
  2. open parentheses r subscript 1 over r subscript 2 close parentheses squared
  3. r subscript 2 over r subscript 1
  4. open parentheses r subscript 1 over r subscript 2 close parentheses squared

The correct answer is: r subscript 2 over r subscript 1
