Electric intensity is directed along the direction at which electric potential

Electric field is directed along the direction in which rate of electric potential is .......

Define electric field intensity and electric potential.Then prove that electric field intensity is negative gradient of electric potential

A proton is placed in a unifrom electric field directed along the positive x-axis. In which direction willl it tend to move?

Electric field intensity is zero at a point. Is electric potential exist at the point?

Is there a point in an electric field where electric field intensity is zero but not the electric potential ?

If the intensity at a point in an electric field is zero, will the electric potential be also zero at that point? If the electric potential be zero at a point, will the intensity be also zero at the point?

Can there be electric intensity at a point with zero electric potential ? Give an example.

A uniform electric field and a uniform magnetic field are acting along the same direction in a certain region. If an electron is projected along the direction of the fields with a certain velocity then
