Answer:
The normal reaction is the force exerted by an object to prevent the weight/force exerted by another object in contact with it. Therefore it's magnitude will be same as that of the force exerted and it will be perpendicular to the surface of contact of the two bodies.
Limiting friction is the amount of Friction that can be exerted between two surfaces is limited and if the forces acting on the body are made sufficiently great, motion will occur. Hence, 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
Pls mark me the brainliest!!!!
Take care

When two static surface comes to contact to each other then the friction generate. This friction is called limiting friction. When the object is on the point of sliding then the limiting friction generate. The limiting friction is the product of the normal force and coefficient of limiting friction.please mark me as the brainliest please
