A block of weight 100 N is lying on a rough horizontal surface. If coefficient of friction is 1/√3. The least possible force that can move the block is
Answers
Answer :
Weight of block = 100N
Coefficient of friction = 1/√3
We have to find the least possible force that can move the block
★ The least possible force that can move the block is maximum static friction force.
We know that, maximum static friction force is directly proportional to the normal reaction on body.
- f ∝ N
- f = μ × N = μ × mg
μ denotes coefficient of friction
mg denotes weight of body
⭆ f = μ × (mg)
ATQ, weight = mg = 100N
⭆ f = 1/√3 × 100
⭆ f ≥ 57.8N
Cheers!
