Question

The force of friction is maximum when the object is -
a) at rest
b) at the verge of motion
C) moving
d)the friction remains same in all condition

Please tell the correct answer .​

Answer 1

Answer:

at rest

Explanation:

at rest as static friction is the highest. static friction comes into play when we try to move an object at rest.

Answer 2

Answer:

d

Explanation:

The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.

We define limiting friction as the friction which is exerted when equilibrium is on the point of being broken by one body sliding on another.

Hence, the maximum force of friction when the body is just beginning to move is known as the limiting friction.
