Question #97217

Answer 1

`1 kgwt` is the weight of a mass of `1kg` and is equal to `9.81 N` according to `w=mg`, where `w` is weight, `m` is mass and `g` is acceleration due to gravity.
The spring balance has graduations in `0.5kgwt` which is equal to `(9.81*0.5) = 4.91N`
The block starts moving when the pointer is at the `25th` division, which is equal to `(4.91*25) = 122.6N` correct to 1 decimal place.
