Three blocked `A,B` and `C` are placed one over the other as shown in figure. Draw free body diagram of all the three blocks.

Text Solution

Verified by Experts

Free body diagram of `A,B` and `C` are shown below.

Here `N_(1) = `normal reaction between `A` and` B`
`N_(2) = `normal reaction between B and C
and `N_(3) = `normal reaction between `C` and ground.
