The pitentil energy of a satellite is given as `PE= lambda(KE)` where PE = potential energy of the satellite KE = kinetic energy of the satellite The vlaue of constant `lambda` isA. `-2`B. 2C. `-1//2`D. `+1//2`

Answer» Correct Answer - A
PE of satellite `=(GmM_(E))/(R_(E)+h)`
`KE of satellite =1/2 (GmM_(E))/(R_(E)+h)`
KE of satellite `=1/2 (GmM_(E))/(R_(E)+h)`
`PE=-2 KE rarr lambda =-2`
