If the electric field is given by 26i – k. Calculate the electric flux through a surface of area 20 units lying in x-y plane.
The direction of force on a negative charge placed at any point in an electric field is given by
Force F = q×E, where q is the charge and E is electric field.
When charge is negative, then F = -q×E, i.e., force is in opposite direction of electric field
Electric flux through an area dA for an electric field E is given by
A neutral point lies at the centre of the line joining the charges when
Neutral point due to a system of two like point charges For this case neutral point is obtained at an internal point along the line joining two like charges.Here neutral point lies outside the line joining two unlike charges and also it lies nearer to the charge which is smaller in magnitude.
Choose the correct statement:
Electric flux is a _______ quantity
Electric flux is a scalar quantity. Electric Flux is dot/scalar product of magnetic field vector and area vector. And the result of a dot/scalar quantity is always a scalar quantity. So electric flux is also a scalar quantity
If the electric field is given by 6i+3j+4k calculate the electric flux through a surface of area 20 units lying in y-z plane.
Area = 20 i since it is in the Y-Z plane
E = 6i+3j+4k
E.S = Flux
=20*6 = 120 units
Electric lines of force never intersect each other because
Electric lines of force never intersect each other because at the point of intersection, two tangents can be drawn to the two lines of force. This means two direction of electric field at the point of intersection, which is not possible.
Dimensional formula of ØE is
Flux= E. A
-> E= F/q= N/C
-> flux= N/C×m²
Electric flux density is a function of _______
Electric flux density is the charge per unit area. Hence it is a function of charge and not any of the other values.
