Q. 27 What is the angle between the equatorial plane and the orbital plane of:

(a) polar satellite?

(b) geostationary satellite?

Hint: Recall the definition of polar and geostationary satellites.

Step 1: Find the plane of polar and geostationary satellites.

Consider the diagram where the plane of geostationary and polar satellites are shown.

Step 2: Find the angle between the equatorial plane and the orbital plane.

Clearly,
(a) Angle between the equatorial plane and orbital plane of a polar satellite is 90°.

(b) Angle between the equatorial plane and the orbital plane of a geostationary satellite is 0°,
