Answer:
The minimum force is required is, f = 0.3 mg Newton
Explanation:
Given data,
The coefficient of the static friction, μₓ = 0.3
Let the mass of the wheel is, m = M kg
The minimum force required to set the wheel in motion is equal to the force of static friction. This amount of force can be applied tangentially to the wheel in a vertical direction to set the wheel in motion.
Fₓ = μₓ. F
Where F is the normal force acting on the wheel and it is equal to mg.
Therefore, the minimum force is required is, f = 0.3 mg Newton
