Is there any effect on effective gravitational constant if there is drastic change in extra-dimension which is a function of time?

Let us consider five dimensional Kaluza-Klein metric which is given below ds2 = -dt2 + R2(t)[{dr2/(1-kr2)}+ r2 d(theta)2+ r2sin2(theta)] + A2(t)d2(phi) Here k, R(t) and A(t) are curvature...
