SSC SSC JE Mechanical 2025 Mock Test Series (Paper 1 & Paper 2) Engineering Mechanics Equilibrium and Friction Friction
Pick - out the FALSE statement for laws of kinetic friction.
1
The constant ratio that magnitude of kinetic friction bears is slightly greater than that in case of limiting friction
2
The magnitude of kinetic friction bears a constant ratio to the normal reaction between the two surfaces
3
For moderate speeds, the force of friction remains constant. But it decreases slightly with the increase of speed
4
The force of friction always acts in a direction, opposite to that in which the body is moving
