Get the linear acceleration
of center of sphere denoting it as y 
then the vertical gravitation would be x 
To look for the angle of inclination which is b we
do the following steps:
90 - b = a 
so cosine(a)= x/y 
cosine(a)= (.24g)/g 
a = 76 degrees (by using calculator or trig
table) 
then b would be = 14 degrees
