Question

Orbital velocity of a satellite in its orbit (around earth) of radius 'Y' is 'v'. it collides with another body in it orbit
and comes to rest just after the collision. Taking the radius of earth as R, the speed with which it will fall on the
Valt
surface of earth will be v, al - b)
R
(A) a = 1
(B) a = 2
(C) b = 1
(D) b = 2

Answer 1

Answer:

sorry this is a good qui but I know that

Answer 2

Answer:

(B) and (C)

Explanation:

Using Energy Conservation

-GMm/r = -GMm/R + mv*²/2

v*² = 2GM ( 1/R - 1/r )

v* = √ GM/r . √ 2 (r /R - R/R)

v* = v √2 (r/R - 1)

Hence, a = 2 , b = 1
