which graph best represents the variation of radius R of a circular orbit of satellite against its time period

graph 3 or 4
  • -17
1 may be
  • -17
F grebes j
  • -7
4th graph is correct ..
Because...
T =2?/R. {(R+h)^3/g}^1/2

=>T =2? {(R+h)^3 /GM}^1/2

=> T is directly propotional to
{R+h}^3/2. i.e r^3/2

=> T is propotional to r^3/2
=> T= kr^3/2
=> x= k y^3/2
  • -6
T directly proportional to (r+h)^2/3 So with increase in T r increase but less
  • -3
3 is the correct answer
  • 0
4 will be the correct answer
  • 1
option 4
  • 1
