Question 1
1 / -0

The electrostatic field due to a charged conductor just outside the conductor is

A
zero and parallel to the surface at every point inside the conductor

B
zero and is normal to the surface at every point inside the conductor

C
parallel to the surface at every point and zero inside the conductor

D
normal to the surface at every point and zero inside the conductor

Solution

The electrostatic field due to a charged conductor just outside the conductor is normal to the surface at every point and zero inside the conductor.
Question 2
1 / -0

If the distance between a point charge and an infinitely large charge plate is increased by factor 2, the new force on the point charge will be

A
decreased by factor 4

B
increased by factor 2

C
decreased by factor 2

D
the same

Solution

Since an infinitely large charged plate will create an uniform field (constant), therefore the force remains the same.
