Question
Two identical satellites are at the heights R and 7R from the Earth′s surface. Then which of the following statement is incorrect : - (r = radius of the Earth)
Options
A.Ratio of total energy of both is 5
B.Ratio of kinetic energy of both is 4
C.Ratio of potential energy of both 4
D.Ratio of total energy of both is 4 and ratio of magnitude of potential to kinetic energy is 2
Solution
K.E. = + 
r = 2R for the first and r = 8R for the IInd
= 4 : 1
Similarly P.E. is ⇒ -
= 4 : 1
Put the ratio of
= 2
r = 2R for the first and r = 8R for the IInd
= 4 : 1Similarly P.E. is ⇒ -
= 4 : 1Put the ratio of
