1.	Two blocks are kept on an inclined plane and tied to each other with a mass-less string. Coefficient of friction between m_(1) and inclined plane is mu_(1) & that betweeb m_(2) & the inclined is mu_(2). Then :
Answer» The tension in the string in ZERO if `mu_(1) gt mu_(2)` The tension in the string is zero if `mu_(1) LT mu_(2)` Tension in the string is ALWAYS zero irrespective of `mu_(1) & mu_(2)` NONE of these Answer :d
