Answer» The reading of the spring balance will be sum of the tension in the strings on the either side. so, for tension firstly we will calculate acceleration as. total force = (60-30) = 30Nmass = (6+3) = 9kg. so acceleration is = 30/9 now , for tension on 6kg string the equation is 60-T = maor T = 60-6(30/9) = 60-20 = 40N. tension on 3kg string is 30-T = m(-a)30-T = - 3*(30/9) = -10 or T = 40N so total T = T+T =80N the reading is 80N

Answer»

The reading of the spring balance will be sum of the tension in the strings on the either side.

so, for tension firstly we will calculate acceleration as. total force = (60-30) = 30Nmass = (6+3) = 9kg.

so acceleration is = 30/9

now , for tension on 6kg string the equation is 60-T = m*aor T = 60-6*(30/9) = 60-20 = 40N.

tension on 3kg string is 30-T = m(-a)30-T = - 3*(30/9) = -10 or T = 40N

so total T = T+T =80N

the reading is 80N
