A man of mass `40kg` is at rest between the walls as shown in the If `'●'` between the man and the walls is `0.8` find the normal reactions exerted by the walls on the man .

Text Solution

Verified by Experts

Since man is at rest,

`N_(1) - N_(2) = 0 ` (horizontally equilibrium)
`therefore " " N_(1) = N_(2) = N, F_(1) = F_(2) = F` (say)
`therefore " " 2 mu N` = mg (vertically equilibrium )
`= 2 xx 0.8 xx N = 400`
`therefore " " N = 250 N `
