Question

A satellite is seen after each 8h over the equator at a place on the earth when its sense of rotation is opposite to the earth. The time interval after which it can be seen at the same place when the sense of rotation of the earth and the satellite is the same will be
  1. 8h
  2. 24h
  3. 12h
  4. 6h

A
8h
B
24h
C
12h
D
6h
Solution
Verified by Toppr

The time period is given by,
T=2πω
Angular Velocity is given by,
ω=2πT
and then find relative angular velocity
Given 8=2πω1+ω2=2π2πT1+2πT2
