Form the ree bdoy diagrams,
`T+0.5a-0.5g=`……………i
`muR+1a+T_1-T=0` …ii
`muR+1a-T_1=0`
muR+a=T_1`………..iii
From equations ii and iii we have
`muR+a=T-T_1`
`rarr T-T_1=T_1`
`rarr T=2T_1`
Equation ii becoems `muR+a+T_1-2T_1=0`
`rarr muR+a-T_1=0`
`rarr T_1=muR+a`......iv
`Equation i. becomes `2T_1+0.5a-0.5g=0`

`rarr T_1=(0.5g-0.5a)/2
`=0.25g-0.25a`
From equatins iv and v
`0.2g+a=0.25g-0.25a`

`rarr a=0.05/1.25xx10
`=0.4xx10 m/s^2`
`[g=10m/s^2]`
a. Aceleration of 1 kg block each is0.4 `m/s^2`.
b. Tension `T_1=0.2g+a+0.4=2.4N`
c. t=0.5-0.5a`
`=0.5xx10-0.5xx0.4`
`4.8N`
