Question

Which of the following is not true with respect to Critical velocity? *



(1)It depends on the mass of the satellite

(2)As the height of the satellite from the earth's surface increases, the critical velocity decreases.

(3)The critical velocity is in a tangential direction to the orbit around the earth.

(4)As the height of the satellite from the earth's surface decreases, the critical velocity increases.

​

Answer 1

Answer:

The cricital velocity of a satellite is independent of the mass of the satellite. It is given by the expression v=

(GM/r)

. It only depends on the mass of the earth

Answer 2

Option 3 The critical velocity is in a tangential direction to the orbit around the earth..
