A wooden block is pressed on a wall. The coefficient of friction between the wall and wood is `0.35`. If the mass of the wood is `1kg` then calculate the force of reaction required to hold the block on the wall which just causes sliding. `(g=9.8ms^(-2))`.

Text Solution

Verified by Experts

Given, `m=1kg`, `mu_(s)=0.35`, `g=9.8ms^(-2)`
`f=mg=muF`
`:.F=(mg)/(mu)`
`F=(1xx9.8)/(0.35)`
`F=28N`
Force required to hold the block agains the wall without skidding is `28N`.
