Can you explain the answer of this question below:Which of the following quantity is a scalar?A:TorqueB:Dipole momentC:Electric FluxD:Electric Field IntensityThe answer is c.

Question

Answer

Yeah scalar is electric flux...as it is the dot product of Electric field 'E'✗ section areaA....FLUX=E.A Torque=r×F(((cross product of perpendiculr dis &force.)))....vector... dipole moment &electric field r also vectors...

Answer

Option c

Answer

Electric flux is a scalar quantity. It is a scalar because it is the dot product of two vector quantities, electric field and the perpendicular differential area.

Answer

Electric Flux as a Scalar Quantity
Electric flux is a scalar quantity because it is defined as the dot product of the electric field vector and the area vector. The electric flux passing through a surface is a measure of how many electric field lines pass through that surface. This quantity only has magnitude and no direction associated with it.

Differences between Scalar and Vector Quantities
- Scalar Quantity: A scalar quantity is defined by its magnitude only, without any direction associated with it. Examples include mass, temperature, and electric flux.
- Vector Quantity: A vector quantity is defined by both magnitude and direction. Examples include force, velocity, and electric field intensity.

Electric Flux Calculation
The electric flux through a closed surface is given by the equation:
$$ \Phi = \int \vec{E} \cdot d\vec{A} $$
Where:
- $ \Phi $ is the electric flux
- $ \vec{E} $ is the electric field vector
- $ d\vec{A} $ is the differential area vector

Conclusion
In conclusion, electric flux is a scalar quantity because it does not have a direction associated with it. It is determined solely by the magnitude of the electric field and the area of the surface through which the field lines pass. This distinction makes electric flux different from vector quantities like torque, dipole moment, and electric field intensity.
