Correct Answer - Option 1 : 0.025
Concept:
An effort is required to overcome friction.
∴ Effort = Friction force
\(Friction\ force\ (F) = μ× P\)
where μ = Coefficient of friction, P = Load/ weight
Calculation:
Given:
F = 25 N, Weight = 1 kN = 1000 N
∴ 25 = μ × 1000
μ = 0.025
Hence the coefficient of friction will be 0.025
