There is an object on the earth's equator that makes circular motion with the rotation of the earth. The centripetal acceleration is A1, the linear velocity is V1, and the angular velocity is W1. The synchronous satellites A2, V2, W2 and Shenzhou-7 A3, V3, W3 are compared, 3Q

Shenzhou-7 is a near earth satellite
According to: GMM / R ^ 2 = MV ^ 2 / r = ma = MW ^ 2R
A = GM / R ^ 2
V^2=GM/r
w^2= GM/r^3
For earth orbiting satellites: synchronous satellite, Shenzhou-7, the larger R is, the smaller a, V and W are
a2 < a3
v2 < v3
w2 < w3
Synchronous satellites and objects on the earth's equator that rotate with the earth
W1 = W2 (if the synchronization period T is equal, W2 is equal)
A = w ^ 2R, R is big, a is big, synchronous satellite R is big, A1 < A2
V = w * r, R big, V big, synchronous satellite r big, V1 < v2
So: A1
