Question

Spring scales are used to measure the weight of large are awkward items in what SI unit

Answer 1

Weight is defined as attraction force of Earth on an object

It is given by formula

F = mg

when spring balance is used to measure the weight of an object then it means

`F_s = F_g`

spring force is balanced by gravitational force

so the unit to measure this force is given by NEWTON(N)

so answer would be Newton(N)
