Question

The following diagram states tstates the three laws of kepler
Answer the following question:
If the area ESF in figure is equal to area ASB , what will you infer about EF?

Answer 1

acc to keplers law of area the planet revolving around the sun sweeps out equal area at equal intervals of time ie the farthest distance of planet from sun called apogyee and closest distance from sun called perigyee thus

accordingly it states that dA/dt =constant

1 more important pts is it is based on law of angular momentum

L=2m(dA/dt) de angular momentum

i hope it is clear if any doubt ask me....
