Question

If we use `100 Omega` and `200 Omega` in place of `R` and `X` we get null pont deflection, `l = 33cm`. If we intercharge the resistors, the null point length is found to be `67 cm` Find end corrections `prop and beta`.

Answer 1

Correct Answer - A::C
`alpha=(R_(2)l_(1)-R_(1)l_(2))/(R_(1)-R_(2))=((200)(33)-(100)(67))/(100-200)=1 cm`
`beta=(R_(1)l_(1)-R_(2)l_(2))/(R_(1)-R_(2))-100`
`=((100)(33)-(200)(67))/(100-200)-100`
`= 1 cm`.
