4. A particle of mass 5 kg is moving on rough fixed inclined plane with constantvelocity of 5 m/s as shown in the figure. Find the friction force acting on a bodyby plane.LA125 N(8) 20 N(D) none of these30°(C) 30 N

Answer»

If the body is in constant velocity, then net force acring on it is zero. Gravity and frictional force are the only forces that are acting here, neglecting air resistance.

Hence, frictional force is equal to Gravitational force.Ff=mgsin30∘=mg/2=5×10/2=25N

not in theory do it numerically
