Two blocks of equal mass m are tied to each other through light string. One of the blocks is pulled along the line joining them with a constant force F. Find the tension in the string joining the blocks.

Explanation

Referring ure 1, `T+ ma-F=0`
Referring ure 2, `T-ma=0,
`rarr T=ma` ………..i,
` rarr F=T+m`
`rarr F= T+ma` ltbr `rarr F=T+T`
` F=T+T`
`rarr 2T=F`
`rarr T = F/2`.
