Two blocks of mass m_(1) and m_(2) (m_(2) gt m_(1)) are placed in contact with each other on an inclined plane as shown in figure . The coefficient offriction between m_(1) and surface is mu_(1) and between m_(2) and surface is mu_(2).

Answer»


SOLUTION :`m_(2) GT m_(1)`

If `m_(1) gt mu_(2)` both BLOCKS will move together as `m_(2) G sin theta gt m_(1) g sin theta `
`therefore ""(a_(2) gt a_(1))`.
If `mu_(1) LT mu_(2)` , both blocks will have different acceleration as `a_(2) lt a_(1)` .
