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

Text Solution

Verified by Experts

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