Test: Electric Field Density - Question 1
Save

The lines of force are said to be

Detailed Solution for Test: Electric Field Density - Question 1

Answer: c
Explanation: The lines drawn to trace the direction in which a positive test charge will experience force due to the main charge are called lines of force. They are not real but drawn for our interpretation.

Test: Electric Field Density - Question 2

Which of the following correctly states Gauss law?

Detailed Solution for Test: Electric Field Density - Question 2

Answer: d
Explanation: The electric flux passing through any closed surface is equal to the total charge enclosed by that surface. In other words, electric flux per unit volume leaving a point (vanishing small volume), is equal to the volume charge density.

Find the flux density of a sheet of charge density 25 units in air.

Detailed Solution for Test: Electric Field Density - Question 3

Answer: b
Explanation: Electric field intensity of infinite sheet of charge E = σ/2ε.
Thus D = εE = σ/2 = 25/2 = 12.5.

Test: Electric Field Density - Question 4
Save

The electric flux density is the
Detailed Solution for Test: Electric Field Density - Question 4

Answer: a
Explanation: D= εE, where ε=εoεr is the permittivity of electric field and E is the electric field intensity. Thus electric flux density is the product of permittivity and electric field intensity.

Test: Electric Field Density - Question 5

A uniform surface charge of σ = 2 μC/m2, is situated at z = 2 plane. What is the value of flux density at P(1,1,1)m? 
Detailed Solution for Test: Electric Field Density - Question 5

Answer: b
Explanation: The flux density of any field is independent of the position (point). D = σ/2 = 2 X 10-6(-az)/2 = -10-6.

Test: Electric Field Density - Question 6

Find the flux density of line charge of radius (cylinder is the Gaussian surface) 2m and charge density is 3.14 units?
Detailed Solution for Test: Electric Field Density - Question 6

Answer: d
Explanation: The electric field of a line charge is given by, E = λ/(2περ), where ρ is the radius of cylinder, which is the Gaussian surface and λ is the charge density. The density D = εE = λ/(2πρ) = 3.14/(2π X 2) = 1/4 = 0.25.

Test: Electric Field Density - Question 7

Find the electric field intensity of transformer oil (εr = 2 approx) with density 1/4π (in 109units) 
Detailed Solution for Test: Electric Field Density - Question 7

Answer: c
Explanation: D = εE. E = (1/4π)/(2Xεo) = 4.5 X 109 units.

Test: Electric Field Density - Question 8
Save

Electric flux density in electric field is referred to as
Detailed Solution for Test: Electric Field Density - Question 8

Answer: b
Explanation: Electric flux density is given by the ratio between number of flux lines crossing a surface normal to the lines and the surface area. The direction of D at a point is the direction of the flux lines at that point.

Test: Electric Field Density - Question 9
Save

If the radius of a sphere is 1/(4π)m and the electric flux density is 16π units, the total flux is given by,
Detailed Solution for Test: Electric Field Density - Question 9

Answer: c
Explanation: Total flux leaving the entire surface is, ψ = 4πr2D from Gauss law. Ψ = 4π(1/16π2) X 16π = 4.
