Here N is the normal force given by the formula. N = mg. g is the acceleration due to gravity = 9.81 m/s2. So N = 50 × 9.81 = 5395.5. Kgm/s2 = 5395.5.
If the coefficient of friction between A and B is μ , the maximum ...
Webrespect to each other, the force of friction comes into play (a) only if the objects are solid. (b) only if one of the two objects is liquid. (c) only if one of the two objects is gaseous. (d) … WebApr 3, 2024 · Rolling friction. Each object receives a contact force; whenever the surface of one object slides over the surface of another. This contact force, which always opposes relative motion between the two surfaces, is called frictional force. The frictional force is applied tangentially to the two-body interface. how to make polythene minecraft
