Question

A block is sliding on a rough horizontal surface. If the contact force on the block is √2 times the frictional force, the frictional force is (Note: N= Normal reaction)
a) 0.25 N
b)1/√2N
c) √2N
d) 1 N​

Answer 1

Answer:

If the contact force on the block is √(2) times the frictional force, ... So, the contact force is normal reaction ... If the coefficient of friction between their surface is 0. 15 then ...
