33its easy...
for (a) balance torque about point of contact.(torque due to mg and T.. T will be known from this)
for (b and c) now T is known. only unknown left are normal reaction from incline and the friction.
balance forces on sphere in two axes. (2 variable 2 equation)..
both (b) and (c) will be known.
