Question

In which of the following cases the contact force between a b is maximum ma mb 1kg g 10ms 2

Answer 1

Answer:

For (A):a=

1+1

50

=25ms

−2

, contact force between A and B =1×25=25N

For (B): For system reaction given by ground =20+30=50N

For block A reaction between A and B =50−10=40N

For (C): For motion of A, N

AB

−10=1×25 ⇒ N

AB

=35N

For (D): For motion of A, N

AB

=1×35=35N
