In a certain region of space, the electric field is zero. From this, we can conclude that the electric potential in this region is:

In a certain region of space the electric potential V is known to be constant. Is the electric field in this region (a) positive (b) zero ,or (c ) negative ?

In a certain region of space the electric potential V is known to be constant. Is the electric field in this region (a) positive (b) zero ,or (c ) negative ?

In a certain region of space the electric field increases radially as $\overrightarrow{E}=90r(-\hat{r})$ .The electric charge contained within a sphere of radius $2m$ centred at the origin is:

In a certain $0.1m^3$ of space, electric potential is found to be 5 V throughout. What is the electric field in this region ?

In a certain region of space electric field E and magnetic field B are perpendicular ot each other and an electron enters region perpendicular to the direction of B and E both and moves undeflected, then velocity of electron is

In a certain region of space electric field E and magnetic field B are perpendicular ot each other and an electron enters region perpendicular to the direction of B and E both and moves undeflected, then velocity of electron is

Assertion: If electric potential remains constant along a path in electric field, then the electric field must be zero.
Reason: The negative of an electric potential gradient in a direction is equal to the component of electric field in that direction.

A graph of the x-component of the electric field as a function of x in a region of space is shown in figure. The $y-\text{and}z-compo\ne nts$ of the electric field are zero in this region. If the electric potential is 10 V at the origin, then the potential at x = 2.0 m is

A certain region of space is to be shielded from magnetic fields. Suggest a method.

In the region where electric field $E=0$, the relation between electirc potential $V$ and distance $r$ is
