ma + f = mgsin30

fr=I\alpha

since body is not to slide

Undetermined error: @@a = alphar@@

I =Undetermined error: @@(2mr^2)/3@@

therefore f = Undetermined error: @@(2ma)/3@@ ....1

Undetermined error: @@a = (gsin30)/(5/3)@@

Undetermined error: @@f = mumgcos30@@ .....2

equate 1 and 2

u get ans as Undetermined error: @@2/(5.3^0.5)@@
