Question

In the diagram shown in figure, match the following `(g=10 m//s^(2))`

`{:(,"Column-I",,,"Coloumn-II"),((A),"Acceleration of 2kg block",,(P), "8 Si unit"),((B),"Net force on 3kg block",,(Q),"25 SI unit"),((C),"Normal reaction between 2 kg and 1kg",,(R),"2 SI unit"),((D),"Normal reaction between 3 kg and 2kg " ,,(S)," 45 SI unit"),(,,,(T)," None"):}`

Answer 1

Correct Answer - R
T
Q
T
(A) `a=(42N-6xxgxxsin 30^(@))/6=2 m//s^(2)`

(B) `F_("net")` on 3kg =3xa=6N
(C) `R_(1)-1xx g sin 30^(@)-18=1xxa`
`R_(1)=18+5+2=25 N`
`(D) 60 N-R_(2)-3xxg sin 30^(@)=3xx2`
`R_(2)=60-15-6=39N`
