Solution
The correct option is B 15 kg
The Spring balance shows a reading corresponding to the force at any one end of the Spring balance.At any instant , the force at the two ends will be equal in magnitude. Other wise , the balance will be in a motion , decided by the resultant force.
The spring will show a reading of 15kg.
