1 Laws of Motion
A block of mass m is placed on a wedge. The wedge can be accelerated in four manners marked as (1), (2), (3) and (4) as shown. If the normal reactions in situation (1), (2), (3) and (4) are N1 ,N2 ,N3 and N4 respectively and acceleration with which the block slides down relative to the wedge in situations are b1, b2 , b3 and b4 respectively then:
A)N3 > N1 > N2 > N4 B)b2 > b3 > b4 > b1 C) b2 > b3 > b1 > b4 4D) N4 > N3 > N1 > N2
1) AB 2) CD 3) AC 4) ABC
