In figure shown minimum mass of block `B (` at a particular angle between horizontal and string `AP )` to just slide the block `A` on rough horizontal surface is `(m)/(2)` as shown in figure. If `mu` is the coefficient of friction between block `A` and ground then `(p)/(mu^(2))` will be `:`

Answer

3

Explanation

Minimum for required.
`rArr (mu mg )/(sqrt(1+mu^(2)))=(mg)/(2)`
`mu=(1)/(3)`
`mu^(2)=(1)/(3)`
`(1)/(mu^(2))=3`
