हिन्दीConsider the following statements regarding the energies of an Earth satellite in a circular orbit of radius \( r \) (\( r = R_E + h \)): (A) Kinetic energy \( K.E. = \frac{G M_E m}{2r} \) (B) Potential energy \( P.E. = -\frac{G M_E m}{r} \) (C) Total energy \( E = -\frac{G M_E m}{2r} \) (D) \( K.E. = -2E \) Which of the above statements are correct?
Correct answer · Option 2
(A), (B) and (C) only
Explanation
\( K.E. = -E \), not \( -2E \), so statement (D) is incorrect. Statements (A), (B), and (C) are correct.
