A small object slides without friction from the height H = 50cm

A small object slides without friction from the height H = 50cm as shown in the figure. It loops the vertical loop of radius 20 cm from which a symmetrical section of angle 2a has been removed. The angle a such that after losing contact at A and flying through the air, the object will reach at point B is . The value of n is
