Comprehension # 1 If net force on a system in a particular direction is zero (say in horizontal direction) we can apply: Sigmam_(R )x_(R )= Sigmam_(L)x_(L), Sigmam_(R )v_(R )= Sigmam_(L)v_(L) and Sigmam_(R )a_(R ) = Sigmam_(L)a_(L) Here R stands for the masses which are moving towards right and L for the masses towards left, x is displacement, v is veloctiy and a the acceleration (all with respect to ground). A small block of mass m = 1 kg is placed over a wedge of mass M = 4 kg as shown in figure. Mass m is released from rest. All surface are smooth. Origin O is as shown. Normal reaction between the two blocks at an instant when absolute acceleration of m is 5 sqrt3 m//s^(2) at 60^(@) with horizontal is ......... N. Normal reaction at this instant is making 30^(@) with horizontal :-
