Question

A satellite revolves around a planet (P) in an elliptical orbit. It goes from A to B in time t1 and C to D in time t2. If area swept by radius vector area (ABP) = 2 area (CDP), then

Answer 1

Explanation:

Lettheheightofconehmetre

⇒Totalareaofgroundwillberequired

=5×16m2=80m2=5×16m2=80m2

⇒Totalvolumeofairisneeded

⟹100×5m3=500m3

Accordingtothequestion

⇒Volumeofcone

=500m3

⇒13areaofground×height=500

⇒13×πr2×h=500

⟹13×80×h=500

⇒Height=500×380

⇒Heightofcone

⟹18.75metres
