Satellites orbiting the earth have finite life and sometimes debris of satellites fall to the earth. This is because,
A
The solar cells and batteries in satellites run out.
B
The laws of gravitation predict a trajectory spiraling inwards.
C
Of viscous forces causing the speed of satellite and hence height to gradually decrease.
D
Of collisions with other satellites.
Answer
Of viscous forces causing the speed of satellite and hence height to gradually decrease.
Explanation
Solution
Of viscous forces causing the speed of satellite and hence height too gradually decreases.
