The blocks are attached by an inextensible light string and pulled vertically upward by force `100N` as shows. Find the common acceleration and tension in the string

Text Solution

Verified by Experts



`uarr:100-20-T=2a`
`uarr:T-30=3a`
Adding (i) and (ii), we get
`50=5arArra=10m//s^(2)`
`T=60N`
Note`:` Don't forget to include weight in the free body diagram.
