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 Vm^-1, -200 Vm^-1`
B. `-100 Vm^-1, + 200 Vm^-1`
C. `+ 200 Vm^-1, + 100 Vm^-1`
D. `-200 Vm^-1, - 400 Vm^-1`

Answer

b

Explanation

`E_x = - (-2 V)/(-2 xx 10^-2 m) = -100 Vm^-1`
`E_y = -(-2 V)/(1 xx 10^-2 m) = 200 Vm^-1`
Time - saving solution
clearly, x- component is negative and y - component is positive.
