In elliptical orbit of a planet, as the planet moves from apogee position to perigee position to perigee position, match the following columns
`{:(,"Column-I",,"Column-II"),("(A)","Speed of planet","(p)","Remains same"),("(B)","Distance of planet from centre of sun","(q)","Decreases"),("(C)","Potential energy","(r)","Increase"),("(D)","Angular momentum about centre of sun","(s)","Cannot say"):}`

Text Solution

Verified by Experts

The correct Answer is:
`(A rarr r,B rarr q, C rarr q,D rarr p)`
In the figure given alongside, it can be seen that at perigee position, plant is nearest to the sun. So, in the elliptical moves, as the planet orbit from opogee position to perigee position, then speed of planet increases, distance of planet from cebtre of sun decreaes, potential energy decreases, Angular momentum about centre of sun remains the same
