There is a box of 70 kg on a rough surface and Ram is just able to pull the box by applying a force of $F_{1}$ (Figure1) Avinash tries to pull the same box but in different orientation (figure (ii)). He had to apply force $F_{2}$ is order to just move the box. Who had to apply a lesser force in order to just move the box?

Solution

The correct option is C
(a)Both applied same force

Ram's Case :-

So to be able to move it

$F_{1}$ $\geq$ fr

Fr = $μ$ N = $μ$ 70g

$F_{1}$ $\geq$ $μ$ 70g

$F_{1}$ = $μ$ 70g

Avinash's case:-

$F_{2}$ $\geq$ fr

$F_{2}$ $\geq$ $μ$ 70g

$F_{2}$ = $μ$ 70g

So to just move the blocks the force was same.

The correct option is C (a)Both applied same force Ram's Case :- So to be able to move it F1 ≥ fr Fr = μN = μ 70g F1 ≥ μ 70g F1= μ 70g Avinash's case:- F2 ≥ fr F2 ≥ μ70g F2 = μ70g So to just move the blocks the force was same.
