In the diagram shown in figure, all pulleys are smooth and massless and string are light. Match the following columns.

`{:("Column I","Column II"),("(A) 1kg block","(p) will remain stationary"),("(B) 2 kg block","(q) will move down"),("(C) 3 kg block","(r) will move up"),("(D) 4 kg block",(s) 5 ms^(-2)),(,(t) 10 ms^(-2)):}`

Text Solution

Verified by Experts

The correct Answer is:
A`rarr`(r,t),B`rarr`p,C`rarr`q,D `rarr`(q,s)
Since the pulleys are smooth, net force on each pulley should be zero. With this concept, tensions on all strings are shown below.

Now, we can draw free body diagram of all the four blocks.
