To find the coefficient of static friction between the block and the plane, we need to use the formula:

μs = tan(θ)

Where μs is the coefficient of static friction and θ is the angle of inclination at which the block just begins to slide.

First, we need to find the force of gravity acting on the block:

Fg = m*g
Fg = 4 Kg * 9.8 m/s^2
Fg = 39.2 N

Next, we need to find the force of friction acting on the block at the angle of inclination when it just begins to slide. This force is equal and opposite to the component of the force of gravity parallel to the plane:

Ff = Fg*sin(θ)

Ff = 39.2 N * sin(15 ∘)
Ff = 10.1 N

Finally, we can use the formula for the coefficient of static friction to find the answer:

μs = tan(θ)
μs = tan(15 ∘)
μs = 0.27

Therefore, the coefficient of static friction between the block and the plane is 0.27.
