Homework Statement
There was a question in which an object was released upwards from Earth with a velocity of ## 2\sqrt {gR}##.
Using conservation of energy I found that the speed of the body in the orbit was ## \sqrt {2gR} ##
Everything's fine till now. But then I wanted to find the height at which the body was traveling from the centre of the earth.
Homework Equations
Equating centripetal force and gravitational force
v is the speed of body
m is mass of body.
R is radius of earth.
The body is at a height of h from the center of the earth.
To find h.
The Attempt at a Solution
h is coming out to be less that R. How is that possible?
