Question 402: Gravitation

Question

The kinetic energies of
a planet in an elliptical
orbit about the Sun, at
positions A, B and C are
KA, KB and KC, respectively. AC is the major
axis and SB is perpendicular to AC at the position
of the Sun S as shown in the figure. Then

Accepted Answer

Speed of the planet will be maximum when
its distance from the sun is minimum as mvr =
constant.
Point A is perihelion and C is aphelion.
Clearly, V
A
> V
B
> V
C
So, K
A
> K
B
> K
C

Answer

KA < KB < KC

Answer

KA > KB > KC

Answer

KB < KA < KC

Answer

KB > KA > KC
