What is the angle between electric field and surface?
The angle between the electric field and the equipotential surface is always 90. The equipotential surface is always perpendicular to the electric field.
What is the orientation of angle between the equipotential surfaces and the electric field lines?
The equipotential surfaces are always perpendicular to the electric field. These lines create the equipotential surfaces in three dimensions. No work is required in order to move along an equipotential surface, since such movement is always perpendicular to the electric field.
Why are electric field lines always at 90 degrees to equipotential lines?
Since the electric field lines point radially away from the charge, they are perpendicular to the equipotential lines. … The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines.
What is the angle between the area of vector and electric field?
If the electric field is uniform, the electric flux passing through a surface of vector area S is ΦE=E⋅S=EScosθ Φ E = E ⋅ S = ES cos where E is the magnitude of the electric field (having units of V/m), S is the area of the surface, and θ is the angle between the electric field lines and the normal ( perpendicular ) …
What is the angle between the electric?
On equatorial line, the direction of electric field is reversed to that of angle of axial line. Therefore, the angle between dipole moment and electric field is 180°.
What is the angle between the direction of electric field at an axial point?
The angle between the direction of electric field at any axial point and equatorial point due an electric dipole is 180∘.
Why electric field is always at right angle to the equipotential surface?
this is because there is no potential gradient along any direction parallel to the surface , and so no electric field parallel to the surface. This means that the electric lines of force are always at right angle to the equipotential surface.
When an electric dipole is held at an angle in a uniform electric field?
1) the forces experienced by the 2 charges constituting the electric dipole when placed in an uniform external electric field are equal and opposite in nature, the net force on the dipole is zero. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.
Why are the electric field lines perpendicular at a point on an equipotential surface of a conductor?
An equipotential surface is circular in the two-dimensional. Since the electric field lines are directed radially away from the charge, hence they are opposite to the equipotential lines. Therefore, the electric field is perpendicular to the equipotential surface.
What best describes the direction of the electric field on a spherical equipotential surface?
What best describes the direction of the electric field on a spherical equipotential surface? The electric field must be perpendicular to the surface of an equipotential surface.
