Let the speed of the planet at the perihelion P in figure be v_(P) and the Sun planet distance SP be r_(P) . Relater r_(P), v_(P) to the corresponding quantities at the aphelion (r_(A),v_(A)) . Will the planet take equal times to transverse BAC and CPB ?

The four planets closest to the Sun are called

A speed of the palnet at the perihelion P be V_(p) and the sun -planet distance SP be r_(P) as shown in fig. Relate {r_(p),v_(p)} to the corresponding quantities at the aphelion {r_(A),V_(A)} . Will the planet take equal times to traverse BAC and CPB?

If the sun and the planets carried huge amounts of opposite charges

For the planet - sun system identify the correct satatement.

STATEMENT -1 : When a planet revolves around Sun in an elliptical orbit, the work done Sun's gravitational force on the planet remains zero for any value of displacement. and STATEMENT -2 : The mechanical energy of Sun planet system remains conserved throughout the motion of planet.
