Question

Can we have surfaces with zero friction ? *


a)No, the friction can be less in some surfaces, but it can never be zero

b)Yes, the friction can be less in some surfaces, but it can never be zero

c)Both

d)none
​

Answer 1

Answer:

if you talking about the motion on surfaces then it's quite true that there is no surface that will be smooth ,so we doesn't have any surface with 0 friction,so. answer is 'a'

Answer 2

Answer:

a) No, the friction can be less in some surfaces but it can never be zero
