The instantaneous voltages at three term...

The instantaneous voltages at three terminals marked X, Y and Z are given by [
`" "V_(x)=V_(0)sinomegat`,
`" "V_(Y)=V_(0)sin(omegat+(2pi)/3)` and
`" "V_(Z)=V_(0)sin(omegat+(4pi)/3)`
An ideal voltmeter is configured to read rms value of the potential difference between its terminals. It is connected between points X and Y and then between Y and Z. The reading(s) of the voltmeter will be

A

independent of the choice of the two terminals

B

`V_(xy)^(rms)=V_(0)`

C

`V_(yz)^(rms)=V_(0)sqrt(1/2)`

D

`V_(xy)^(rms)=V_(0)sqrt(3/2)`
