A potential of `400 V` is applied at the point `A`. The value of resistance `R_(1)=1000 Omega`, `R_(2)=2000Omega` and `R_(3)=1000Omega` are connected between points `A` and `G` as shown in the figure. Point `G` is earthed. The measured potential difference by an ideal voltmeter connected across `R_(2)` is

Options

A. `100 V`
B. `200 V`
C. `300 V`
D. `400 V`

Answer

b

Explanation

The potential of point `G` should be kept zero.
