Reading of spring balance `S_1` and `S_2` (Pulley are ideal)

Options

A. 10 kg, 10 kg
B. 5 kg,5 kg
C. 5 kg, 10 kg
D. 10 kg,5 kg

Answer

C

Explanation

Reading of spring balance is tension in the string.

`T_(2)=10 g =100N`
`2T_(1)=T_(2)`
`T_(1)=50 N`
So reading of `S_(1)` is 50 N or 5 kg
So reading of `S_(2)` is 100 N or 10 kg
