Match the following columns. Codes array llll A & B & C & D array
Options
- AIV II I III
- BIII I IV II
- CII II III III
- DNone of these
Correct answer
D. None of these
Step-by-step solution
The potential energy of satellite at distance r from earth is U= -G M m r So, it is always negative as it is due to attractive gravitation force of earth's field. The kinetic energy of satellite is K= G M m 2 r It is always positive. The total energy of satellite is aligned TE & =K+U= G M m 2 r - G M m r & =- G M m 2 r aligned which is negative. The gravitation potential energy of satellite at infinity is U=- G M m r =- G M m =0 So, the correct match is A II , B II , C I , D III. No option is correct.
