5. A light metre rule is allowed to pivot freely at the zero end. The other end supported by a spring balance. A weight of 200N is then hung at the 40crs mark. The metre rule
stays horizontal, What is the reading on the spring balance?

i think its

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
