Solution

The correct option is D zero
We know that , angle of repose is the maximum angle for the body to be stable in the inclined plane and the tanθ=μ, where μ is the coefficient of friction of the incline plane
Here it is given that angle of repose is θ=39o and incline plane angle is less than angle of repose, hence frictional force is sufficient to hold the block

f1>mg sinθ friction is static
Hence, T=0

Option D is the correct answer
