Question

A solid cube is placed on a horizontal surface. The coefficient of friction between them is where . A variable horizontal force is applied on the cube's upper face, perpendicular to one edge and passing through the mid-point of that edge. The maximum acceleration with which it can move without toppling is

Answer 1

The coefficient of friction between them is where . A variable horizontal force is applied on the cube's ... to one edge and passing through the mid-point of that edge.

Answer 2

Answer:

a=g(1-2u) u is coefficient of friction

Explanation:

from free body diagram,

F- umg=ma

(umgL) ÷2+(FL)÷2 =( NL) ÷2 equation 1

L is length os square

from diagram, N=mg

on substituting the values

ma=mg - 2umg

take m as common and cancelled

a = g - 2ug

take g as common

a = g(1 - 2u).
