FrictionMedium
Question
The coefficient of friction between the block and the horizontal surface is μ as shown in figure. The block moves towards right under action of horizontal force F(figure -a). Sometime later another force P is applied to the block making an angle θ(such that tanθ = μ) with vertical as shown in (figure - b). After application of force P, the acceleration of block shall
Options
A.increase
B.decrease
C.remain same
D.information insufficient for drawing inference.
Solution
∵ μP cos θ = P sin θ
So acceleration of block remains same.
