electric field, an electric property associated with each point in space when charge is present in any form. … The strength of an electric field E at any point may be defined as the electric, or Coulomb, force F exerted per unit positive electric charge q at that point, or simply E = F/q.
What is electric field answer?
Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. The formula of electric field is given as; E = F /Q.
What is electric field Class 12?
Electric field is a force produced by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field. SI unit of electric field is N/C (Force/Charge).
Where is electric field?
The electric field of a point charge can be obtained from Coulomb’s law: The electric field is radially outward from the point charge in all directions. The circles represent spherical equipotential surfaces. The electric field from any number of point charges can be obtained from a vector sum of the individual fields.
What is electric field in simple words?
: a region associated with a distribution of electric charge or a varying magnetic field in which forces due to that charge or field act upon other electric charges.
What is electric field and electric potential write its SI unit?
E is the electric field. … The S.I unit of electric field is V/m. The magnitude of electric potential is the amount of work done in moving a point charge from one point to another against the electric field with negligible acceleration. The SI unit of electric potential is Volts.
What are the units of electric field intensity?
Electric field intensity is a vector field we assign the symbol E and has units of electrical potential per distance; in SI units, volts per meter (V/m).
What is the unit of electric field and why?
The value of the electric field has dimensions of force per unit charge. In the metre-kilogram-second and SI systems, the appropriate units are newtons per coulomb, equivalent to volts per metre.
What are the units for electric force?
The electrical force, like all forces, is typically expressed using the unit Newton. Being a force, the strength of the electrical interaction is a vector quantity that has both magnitude and direction.
What is the unit and dimension of electric field?
Or, E = [M1 L1 T–2] × [I1 T1]–1 = [M1 L1 T–3 I–1]. Therefore, the Electric Field is dimensionally represented as [M1 L1 I–1 T–3].
What is the unit of electric dipole moment?
The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system, that is, a measure of the system’s overall polarity. The SI unit for electric dipole moment is the coulomb-meter (C⋅m).
