MCQ
Consider the given statements and select the correct option which correctly identifies true $(T)$ and false $(F).$
$i.$ When a body is in steady motion on a surface, the force of friction is dynamic friction.
$ii.$ The force of friction between two bodies always acts parallel to the surface in contact with each other.
$iii.$ It is easier to push a lawn roller than to pull.
$iv.$ Limiting friction is greater than sliding friction.
  • A
    $(i)-T, (ii)-F, (iii)-T, (iv)-F$
  • B
    $(i)-F, (ii)-T, (iii)-F, (iv)-T$
  • C
    $(i)-T, (ii)-T, (iii)-T, (iv)-F$
  • $(i)-T, (ii)-T, (iii)-F, (iv)-T$

Answer

Correct option: D.
$(i)-T, (ii)-T, (iii)-F, (iv)-T$
Pushing a lawn roller is harder than pulling it because friction is greater in case of pushing.
