Physics Laws of Motion JEE Main

A light spring balance hangs from the hook of another light spring balance, and a block of mass M kg hangs from the former. Then the true statement about the scale reading is

(A)Both the scales read M/2 kg each
(B)Both the scales read M kg eachCorrect
(C)The scale of the lower one reads M kg and the upper one reads zero
(D)The reading of the two scales can be anything, but the sum of the readings will be M kg

Answer: (B)

Solution

Both spring balances are massless (light) and connected in series supporting the same hanging
