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

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

Q. 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:

both balances will read 5 kg wt

the upper reads 5 kg wt and the lower zero

both of them read 2.5 kg wt each

the readings may be different but add upto 5 kg wt

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