Guys just think logically. Just assume that if you have to pull a weight on a plane.

Which is easier? On an inclined plane or a horizontal one.

Definitely, the answer is on a horizontal plane.

So, the angle should be less than the angle of friction.

Angle of inclination = Angle of friction (only when angle of inclination is less angle of static friction).

In this case the friction force is negligible.

Dileepkumar said:   1 decade ago
If force is acting on a body to move the body, then definitely friction will occur is opposite direction, in the same plane. So the angles are identically equal.

Purnendra said:   1 decade ago
Because both forces will be perfectly opposite to each other if angle is same (vertical component will zero. Total force act in a single direction. ).
