Question

The figure shows a horizontal force acting on a block of mass la on an inclined plane (angle). What is the normal reaction N on the block ?

(a) mg sin θ + F cos θ

(b) mg sin θ - F cos θ

(c) mg cos θ - F sin θ

(d) mg cos θ + F sin θ

Answer 1

Correct option (d) mg cos θ + F sin θ

Explanation :

From the figure, the normal reaction on the block is N = mg cos θ + F sin θ
