A wedge M and a block N are subjected to forces P and Q as shown in the figure. If force P is sufficiently large, then the block N can be raised. The weights of the wedge and the block are negligible compared to the forces P and Q. The coefficient of friction (
) along the inclined surface between the wedge and the block is 0.2. All other surfaces are frictionless. The wedge angle is 30°.
The limiting force P, in terms of Q, required for impending motion of block N to just move it in the upward direction is given as
. The value of the coefficient ‘
’ (round off to one decimal place) isYour answerChoose one option.
