Figure shown two equipotential lies `x, y` plane for an electric field. The scales are market. The `x`-component `E_(x)` and y-component `E_(y)` of the field in the space between these equipotential lines are respectively

Options

A. `+100 V//m, -200 V//m`
B. `-100 V//m, +200 V//m`
C. `+200 V//m, +100 V//m`
D. `-200 V//m, -100 V//m`

Answer

B

Explanation

`E_(x) = - (-2V)/(-2 xx 10^(-2) m) = - 100 Vm^(-1)`
`E_(y) = - (-2V)/(1 xx 10^(-2)m) = 200 Vm^(-1)`
