Answer

2 N

Answer

2 N

Answer

Explanation:

Given data:
- Horizontal force (F) = 10 N
- Coefficient of friction (μ) = 0.2
- Weight of the block (W) = ?

Calculating the weight of the block:
- The force required to hold the block stationary against the wall is equal to the frictional force between the block and the wall.
- The frictional force (Ff) can be calculated using the formula: Ff = μ * N, where N is the normal force acting on the block.
- In this case, the normal force is equal to the weight of the block (N = W).
- Therefore, Ff = μ * W.
- Given that the horizontal force (F) is equal to the frictional force (Ff), we can write: F = Ff.
- Substituting the values, we get: 10 = 0.2 * W.
- Solving for W, we find: W = 10 / 0.2 = 50 N.

Conclusion:
- The weight of the block is 50 N.
