MCQ
A box was pushed equal distance on four different surfaces. The force needed for each surface was recorded in the given table.
Surface
$M$
$N$
$O$
$P$
Force Needed (N)
$670$
$570$
$320$
$500$
On which surface was the friction least?
  • A
    $M$
  • B
    $N$
  • $O$
  • D
    $P$

Answer

Correct option: C.
$O$

Friction opposes the motion of an object. For surface $O$, force needed to push the box is least i.e., $320N$, so it has least friction.
