Question

If a body is projected with a speed less than the escape velocity the body, then the body :

• A. can reach a certain height and may fall down following a straight line path
• B. can reach a certain height and may fall down following a parabolic path
• C. may orbit the earth in a circular path
• D. may orbit the earth in an elliptical orbit

Answer 1

Answer: (A), (B), (C)

The correct options are
A can reach a certain height and may fall down following a straight line path
B can reach a certain height and may fall down following a parabolic path
C may orbit the earth in a circular path

If a body is projected with a speed less than the escape velocity of the body, then the body can reach a certain height and then either fall down in a straight line path or in a parabolic path or it may start to orbit earth in a circular path.
