I found ##0.00268m/s^2~~0.003m/s^2##
Centripetal acceleration is given by:
##a_c=v^2/r##
Where ##v## is the linear velocity and ##r## the radius of the circular orbit.
We assume uniform velocity and a circular orbit; velocity will be:
##v=”distance”/”time”=”circumference”/”period”=(2pir)/T##
Our centripetal acceleration will become:
##a_c=(4pi^2r^cancel(2))/(T^2cancel(r))##
##a_c=(4pi^2r)/(T^2)##
Using your data for the radius and period:
##a_c=(4pi^2*3.6*10^8)/((2.3*10^6)^2)##
##a_c=(39.478*3.6*10^8)/(5.29*10^12)##
##a_c=(39.478*3.6*10^8*10^-12)/(5.29)##
##a_c=(39.478*3.6*10^-4)/(5.29)##
##a_c=(142.1208*10^-4)/5.29##
##a_c=26.86…. *10^-4##
##a_c=0.00268m/s^2##
##a_c~~0.003m/s^2##
