A body of mass 2 kg is kept stationary by pressing to a vertical wall ...
Given:
- Mass of the body (m) = 2 kg
- Force applied to the body (F) = 100 N
- Coefficient of friction between the wall and body (μ) = 0.3
To Find:
- Frictional force (Ff)
Explanation:
The body is kept stationary by pressing it against the vertical wall with a force of 100 N. This force counteracts the force of gravity acting on the body. The frictional force between the wall and the body opposes the motion of the body and prevents it from sliding down the wall.
Calculating the Normal Force:
The normal force (Fn) is the force exerted by the wall perpendicular to the surface of contact. It is equal in magnitude and opposite in direction to the force applied by the body on the wall. In this case, the normal force is equal to the force applied to the body, which is 100 N.
Calculating the Frictional Force:
The frictional force (Ff) can be calculated using the formula:
Ff = μ * Fn
Given that the coefficient of friction (μ) is 0.3 and the normal force (Fn) is 100 N, we can substitute these values into the formula to find the frictional force:
Ff = 0.3 * 100 N
Ff = 30 N
Conclusion:
Therefore, the frictional force between the wall and the body is equal to 30 N. This frictional force opposes the motion of the body and keeps it stationary against the wall.
