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) 75 N
b) 45 N
c) 55 N
d) 65 N

We know that sliding friction is always less than static friction. So, 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

45 N.

So, option (b) is correct.
