1.	Two identical satellites are orbiting are orbiting at distances R and 7R from the surface of the earth, R being the radius of the earth. The ratio of their
Answer» KINETIC energies is 4 potential energies is 4 total energies is 4 All of these Solution :Let `r_(1) and r_(2)` respective the DISTANCE of TWO satellites from the earth's SURFACE `r_(1)=R+R=2R and r_(2)=7R+R=8R` (`because` R is the radius of the earth) Now, `K=(GMm)/(2r)rArr(K_(1))/(K_(2))=(r_(1))/(r_(2))=4` `U=-(GMm)/(r),(U_(1))/(U_(2))=(r_(2))/(r_(1))=4` and `E=-(GMm)/(2r)or(U_(1))/(U_(2))=(r_(2))/(r_(1))=4`.
