17N.2.HL.TZ0.b.ii
There is a proposal to power a space satellite X as it orbits the Earth. In this model, X is connected by an electronically-conducting cable to another smaller satellite Y.
Satellite Y orbits closer to the centre of Earth than satellite X. Outline why
satellite Y requires a propulsion system.
[2]
Markscheme
to stop Y from getting ahead
to remain stationary with respect to X
otherwise will add tension to cable/damage satellite/pull X out of its orbit
