Ram pushes eight identical blocks on the horizontal frictionless surface with horizontal force F. The force that block-1 exerts at block-2 has magnitude `F_(21)` and the force that block-7 exerts on the block-8 is `F_(87)` find `(F_(21))/(F_(87))`

Text Solution

Verified by Experts

The correct Answer is:

`F_(81)=ma`
`F_(21)=7ma`
`(F_(21))/(F_(87))=7`
