**The coefficient of static friction between** a **block** class 11 physics JEE_Main. **The coefficient of static friction between** a **block** of **mass** m and an incline is μ s = 0.3 . What can be the maximum angle θ of the incline with the horizontal so that the **block** does not slip on the plane? If the inclined makes an angle θ **2** with the horizontal, find. Answer (1 of 5): the maximum **static** **friction** body (mu)mg and this case the value will become 0.4*2*10 which will become 8N newton, which is good but 2.5N is the fore which you are applying. As we know that **friction** is unique it only acts or opposes only the amount of force you apply on it until i. .

For **the** **coefficient** **of** kinetic **friction**, **the** force need to maintain the constant velocity was 40 N. Formula is F f = μ k N. 40 N = μ k. 200 N. μ k = 0.2. The two **coefficients** **of** **friction** are μ k = 0.2, μ s = 0.4. Question **2**: Find **Friction** force when the **coefficient** **of** **friction** is 0.3 and and normal force is 250 N? Solution: Given values.
