Question

the electric potential as a function of distance x is shown in figure draw a graph of the electric field strength e as a function of x​

Answer 1

For electric strenght e as function of x

x =2 to x=3

$\frac{dv}{dx} = -k$

$E = \frac{-dv}{dx}$

x = 0 to x = 1

$\frac{dv}{dx} = +k$

x = 1 to x = 2

$\frac{dv}{dx} = 0$
