Type: MCQ-numerical-Hard-Class 11
With what velocity should a particle be projected so that its height becomes equal to radius of earth -
A
(GM/R)^(1/2)
B
(8GM/R)^(1/2)
C
(2GM/R)^(1/2)
D
(4GM/R)^(1/2)
Correct Answer
Option A
Detailed Explanation
To reach a height equal to the radius of the Earth, the velocity required is the escape velocity divided by √2, which is (2GM/R)^(1/2).
