Pls solve this ques using the concept of pseudo force if required....pls
Psuedo force is the virtual force which we assume on the system acting on oppsite to the accceleration.Hence, After drawing FBD of the m block,we getfriction force is acting upwards in wedge plane direction and mgsin37 in wedge planee direction in downwards.ma is the psuedo force which would hence then acts in negative x – direction as accln. is in positive – x direction.Do the components of ma as it is now a force that needs to be componented along friction force.that is:f + macos37 = mgsin37we get,f = 3mg/5 – 0.8mg/5 = > 2.2mg/5
