The normal force on the block at the given inclined plane is 67.61 N.
The given parameters:
- Inclination of the plane, θ = 15.0°
- Weight of the block, W = 70 N
What is Normal force?
The normal force on object is the upward force on the object due to its weight acting downwards.
The normal force on the block is calculated as follows;
Fₙ = mgcosθ
Fₙ = Wcosθ
Fₙ = 70 x cos(15)
Fₙ = 67.61 N
Thus, the normal force on the block at the given inclined plane is 67.61 N.
