Two small satellites are moving in circular orbits around the earth at a distance R and `R + Delta R` from the centre of the earth. If their time period of rotation are T and `T + Delta T ` respectively, then

Options

A. `Delta T = T ( Delta R )/( R )`
B. `Delta T = 3T ( Delta R )/( R ) `
C. `Delta T = (3)/( 2) T ( Delta R )/( R ) `
D. `Delta T = ( 2)/( 3) T (Delta R )/( R ) `

Answer

C
