Question

A spring balance is suspended from a ceiling and another spring balance is attached to the end of the first. A 5 kg mass is hung to the lower balance. If springs arc massless, then:

• A. both balances will read 5 kg wt
• B. the upper reads 5 kg wt and the lower zero
• C. both of them read 2.5 kg wt each
• D. the readings may be different but add upto 5 kg wt

Answer 1

Answer: (A)

As the tension is uniformly transmitted when springs are massless, then both the springs balance will read same 5 kg weight.
