Question

A block of wood of mass 3 kg is resting on the surface of a rough inclined surface.
Angle of inclination of the surface is O as in fig.
iy
Name the forces 1, 2 and 3
ily
If the coefficient of static friction is 0.2, Calculate the value of all the three
forces (Take g = 10 m/s)​

Answer 1

Answer:

Explanation:

Assuming the surface is flat, having no inclination.

Minimum Force (F) required to move the block= ¥N in horizontal direction

Where, ¥ is coffecient of friction

N is normal force which is equal to mg in this case, here m is mass of body and g is value of acceleration due to gravity.

So, F = ¥N = ¥mg = 0.2 × 3 × 9.8 = 5.88 Newton
