Which of the following is true for the figure showing electric lines of force? ($E$ is electrical field, $V$ is potential)
$E_A > E_B$
$V_B > V_A$
$V_A > V_B$
$A$ and $B$ both
The electric potential in a region is represented as $V = 2x + 3y -z$ ; then the expression of electric field strength is
The electric potential $V$ at any point $(x, y, z),$ all in metres in space is given by $V = 4x^2$ volt. The electric field at the point $(1, 0, 2)$ in volt/meter, is
In which region magnitude of $x$ -component of electric field is maximum, if potential $(V)$ versus distance $(X)$, graph is as shown?
Two plates are $2\,cm$ apart, a potential difference of $10\;volt$ is applied between them, the electric field between the plates is.........$N/C$
If on the $x$-axis electric potential decreases uniformly from $60 \,V$ to $20 \,V$ between $x=-2 \,m$ to $x=+2 \,m$, then the magnitude of electric field at the origin
