Questions
A particle of mass m is placed on the smooth face of an inclined plane of mas s M and slope which is free to slide on a smooth horizontal plane in a direction perpendicular to the edge. If the particle slides with an acceleration a, the acceleration of the inclined plane towards right A will be
detailed solution
Correct option is A
As the particle moves down the inclined plane, let a be its acceleration. Now the inclined plane moves horizontally towards right with acceleration A.Considering the vertical component of forces acting on the particle.mg−Rcosθ=masinθ .......(i)For horizontal components the motion of the particle is considered at the accelerated frame. So a horizontal fictious force acts opposite to A. This pseudo force mA acts towards the left.Rsinθ+mA=macosθRsinθ=m(acosθ−A) ......(ii)Now consider the force on inclined plane. The forces are shown in figure.Rsinθ=MA .....(iii)Rcosθ+Mg=S .........(iv) From equations (ii) and (iii), we get A=macosθ(M+m)Talk to our academic expert!
