A small box resting on one edge of the table is struck in such a way that it slides off the other edge, 1 m away, after 2 seconds. The coefficient of kinetic friction between the box and the table -

A

Must be less than 0.05

B

Must be exactly zero

C

Must be more than 0.05

D

Must be exactly 0.05

Text Solution

Verified by Experts

The correct Answer is:
A
`s = (1)/(2) at^(2) implies 1 gt (1)/(2) mu .g2^(2) implies mu lt (1)/(20)`
