Python Need help to assign function values to every grid point having the same radius

[bruvcandothis]

Need all the points on the circle to have the same value as at (x , 0)
Any ideas?

import numpy as np
from matplotlib import pyplot as plt
N = 1001
R = np.linspace(1000, 2000, N)
t = np.linspace(0, 2 * np.pi, N)
x = []
y = []

for i in range(N):
    for j in range(N):
        x.append(R[i]*np.cos(t[j]))
        y.append(R[i]*np.sin(t[j]))

fig, ax = plt.subplots()
ax.plot(x, y)
r=1000
def t(x):

    return 0.14*(r**0.74)*(np.abs(x/r)**(-3))


plt.show()
