प्रश्न
Two satellites of masses m1 and m2 (m1 > m2) are revolving round the earth in circular orbit of radii r1 and r2 (r1 > r2) respectively. Which of the following statements is true regarding their speeds v1 and v2?
विकल्प
v1 = v2
v1 > v2
v1< v2
`"v"_1/"r"_1 = "v"_2/"r"_2`
MCQ
उत्तर
v1< v2
Explanation:
`"v" = sqrt ("GM"/"r")`
v is independent of mass of the satellite.
`"v"_1/"v"_2 = sqrt("r"_2/"r"_1)`
`therefore "v"_2 > "v"_1` `[ because "r"_1 > "r"_2]`
