The block A is kept over a plan B. The maximum horizontal acceleration of the system in order to prevent slipping of A over B is `a = 2 ms^(-2)` find the coefficient of friction between A and B

Explanation

For the block `A , f_(max) = ma_(max)`
`a_(max)` of `A =` maximum acceleration of plane in order to have no slipping between A and B
`:. f_(max) = mu mg :. mu mg = ma_(max)`
`:. mu = (a_(max))/(g) = (2)/(10) = 0.2`
