relation bw accleration due to gravity & angular velocity of earth is given by


geff  = g - w2Rcos@


at equator , @ = 0 ,


R(radius of earth = 6400km &


w = 2pi/T  (T is time of rotation of earth = 24hrs)


after putting these values


geff = 9.76m/s2


 


if earth stops then w becomes 0 &  then


geff = g - 0 = g = 9.8m/s (increased)


change in g = 9.8-9.76 =0.04


percentage change = 0.04/9.76 *100 = 0.4%
