Question

A block is sliding on a rough surface .if the contact force on the block is root 3 times the frictional force is(N is normal)
a)0.5
b)root 2
c)1/root2
d)N

Answer 1

Answer:

So, the contact force is normal reactionSo, N = √(2) × f N = normal reaction f = frictional force mg = √(2) × mu × mg mu = 1√(2)
