Question

A satellite is in an elliptical orbit around the earth with aphelion of 6R and perihelion of 2R. Find the eccentricity of the orbit.

1. 1/6

2. 1/3

3. 1/2

4. 1/4

Pls kindly give the answer and the explanation for the answer...​

Answer 1

2(√2)/3

Explanation:

we know that eccentricity is

√((b²-a²)/a²)

here b=6R

a=2R
