Question

To have better speed a satellite launching station should be..

• A. Near the equitorial region
• B. Near polar region
• C. On the polar axis
• D. At any place

Answer 1

The correct option is A Near the equitorial region

• We know that earth's angular velocity is $w=\sqrt{\frac{g}{R}}$.
  
• But the land mass speed is more at the equatorial point as it is at the farthest distance from the axis of rotation of earth.
• Hence satellite should be launched from the equator to have a greater speed.
