Question

Two satellites of masses 50 kg and 100 kg revolve around the earth in circular orbits of radii 9 R and 16 R respectively, wehre R is the radius of earth. The speeds of the two satellites will be in the ratio
A. `3//4`
B. `4//3`
C. `9//16`
D. `16//9`

Answer 1

Correct Answer - b
`(V_(C_(1)))/(V_(C_(2)))=sqrt((r_(2))/(r_(1)))=sqrt((16R)/(9R))=(4)/(3)`
