A block placed on an incline surface is tied to a spring. The block is kept in a position where the spring is compressed by . When released, the block does not move. Now the block is moved to a position where the spring is stretched by . When the block is released from this position, it once again does not move. Find the smallest possible value of coefficient of friction between the block and the incline for this to be possible. It is given that mass of the block is and spring constant is .
