Question

The largest and shortest distance of the earth from the sun are r1 and r2 its distance from the sun when it is at the perpendicular to the major axis of the orbit drawn from the sun

  1. fraction numerator r subscript 1 plus r subscript 2 over denominator 4 end fraction
  2. fraction numerator r subscript 1 space end subscript r subscript 2 over denominator r subscript 1 plus r subscript 2 end fraction
  3. fraction numerator 2 r subscript 1 space end subscript r subscript 2 over denominator r subscript 1 plus r subscript 2 end fraction
  4. fraction numerator r subscript 1 plus r subscript 2 over denominator 3 end fraction

The correct answer is: fraction numerator 2 r subscript 1 space end subscript r subscript 2 over denominator r subscript 1 plus r subscript 2 end fraction
