A horizontal force of 3.2 N is applied on a 3.7kg block, which rests on a horizontal surface. If the co-efficient of friction is 0.6, find the acceleration produced in the block ?

Verified by Experts

The situation is shown in ure. The forces on the block are

a. `4kgxx10 m/s^2=40N` downward by the earth,
b. N upward by the table
c.20 N towards right by the experiments and
d. f towards left by the table (friction).
As the block is at rest these forces should add up to zero. Taking horizontal and vertical components,
`f=20N and N=40N`
Thus, the table exerts a frictioN/Al (static) force of 20 n on the block in the direction oposite to theapplied force.
`flemu_sN, or Mu_sgef/N or mu_sge05.

A block of mass 2.5 kg is kept on a rough horizontal surface. It is found that the block does not slide if a horizontal force less than 15 N is applied to it.
