576 units

288 units

120 units

144 units

Solution:

What is the expression for the electric field due to a sheet of uniform charge density?

None of the above

(ρ_s / 2πϵ₀) * a_ρ

(1/4πϵ₀) * ρ_s

±ρ_s / 2ϵ₀ * a_N

Solution:

The magnetic field at a distance r from a long wire carrying current I is 0.4 Tesla. The magnetic field at a distance 2r is

0.2 tesla

0.8 tesla

0.1 tesla

1.6 tesla

Solution:

The relationship between the reflection coefficient, K, and the Voltage Standing Wave Ratio, S, is given by:

K = (S - 1) / (S + 1)

K = (S + 1) / (S - 1)

|K| = (S + 1) / (S - 1)

|K| = (S - 1) / (S + 1)

Solution:

What happens when a conductor is connected to one plate of a capacitor?

it starts behaving like a conductor

it becomes a more powerful capacitor

Solution:

Two identical metallic spheres of exactly equal masses are taken. One is given a positive charge of q Coulombs and the other an equal negative charge. Are their masses after charging equal?

Yes, the masses are equal

No, the masses are not equal

Solution:

An electron and a proton are moving on straight parallel paths with the same velocity. They enter a semi-infinite region of uniform magnetic field perpendicular to their velocity. Which of the following is/are true?

They will never come out of the magnetic field region

They will come out travelling along parallel paths

They will come out at different times
