Question

2 equal masses each of 2kg are suspended from a spring balance. reading of spring balance will be

Answer 1

Answer:

same

Explanation:

because because acceleration due to gravity not depend on mass it only depend on height from the ground

Answer 2

Answer:

Reading = 2 kg

Explanation:

[Refer to the attached image to understand the case]

Note that string with which the spring balance is attached is ideal meaning that the Tension Force T will be equal at all the point. Moreover, the mass are also equal in this case. So, for one of the masses;

                  T = Mg

                  T = 2 × 10

                  T = 20 N

Similarly, for the other other mass, tension force, t= 20 N. So, spring balance will correspond to the tension force in both the cases.

The correspondence results that reading will be 2 kg itself implying that the reading won't be affected, it will remain the same.

Hope it helps! ;-))
