Question

The eccentricity of earth's orbit is 0.0167. The ratio of its maximum speed in its orbit to its minimum speed is

• A. 2.507
• B. 1.033
• C. 8.324
• D. 1.000

Answer 1

Answer: (B)

1.033

Answer 2

$\frac { v _ { \max } } { v _ { \min } } = \frac { 1 + e } { 1 - e } = \frac { 1 + 0.0167 } { 1 - 0.0167 } = 1.033$
