WebDec 22, 2014 · The general equation for the force of friction (static or kinetic) is F f = μ ∗ F N, where F f is the force of friction and μ is the coefficient of friction (its value is dependent upon the surfaces … WebMar 23, 2024 · Coefficient of friction = 0.3 Normal force F n = mg = 30 × 10 = 300 N. Static friction can be calculated as: F = μ s × N. F = 0.3 × 300 = 90 N We can see that static frictional force i.e. 90N, is greater than applied force 30 N which means that box will not move from its position.
