Question

If the static friction between two surfaces P and Q is measured to be 50 N, then the sliding friction between these two surfaces is most likely to be :
A. 75N
B. 45N
C. 55N
D. 65N

Answer 1

Answer:

Static friction > Sliding friction

Therefore, sliding friction is most likely to be 45N

I hope this will help you friend.

Answer 2

B. 45N

Explanation:

Friction is a phenomenon which resists motion when an object is rubbed against another. Static frction is between two objects that are not moving. Sliding friction is between two objects when one or both are sliding against each other. Sliding friction is lesser than static friction. Rolling friction is between two objects where one or both of the surface is circular. Rolling friction is less than sliding friction.

So sliding friction should be much lesser than the static friction of 50N.

Option B is the answer.
