Question

A block of mass m is at rest on an inclined plane. The coefficient of static friction is u .The minimum angle of inclination at which the block just being slide down is
​

Answer 1

Answer:

ANSWER

The various forces acting on the block are as shown in the figure.

From figure

mgsinθ=f ............(i)

mgcosθ=N .........(ii)

Divide (i) by (ii), we get

tanθ=

N

f

=

N

μN

or θ=tan

−1

(μ)
