Question

Potential due to a system of charge is v= 3+2x in si system what will be the value of electric field at x=2m?

Answer 1

Hope this may be help you

Answer 2

The electric field due to the given potential is (-2 N/C).

Explanation:

It is given that, the potential due to a system of charge is given by :

$V=3+2x$

The electric field and electric potential is given by together as :

$E=\dfrac{-dV}{dx}\\\\E=\dfrac{-d(3+2x)}{dx}\\\\E=-2\ N/C$

The electric field at x = 2 m,

E = -2 N/C

So, the electric field due to the given potential is (-2 N/C).
