Test: Electric Field Lines (NCERT) - Question 3

Which of the following figure represents the electric field lines due to a single negative charge?

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 3

The field lines of single negative charge are radially inward.

Test: Electric Field Lines (NCERT) - Question 4

Which of the following figures correctly shows the top view sketch of the electric field lines for a uniformly charged hollow cylinder as shown in figure?

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 4

For a uniformly charged hollow cylinder, the electric field lines are as shown in figure (b).

Test: Electric Field Lines (NCERT) - Question 5

Figure shows the electric field lines around three point charges A, B and C. Which of the following charges are positive?
 
 

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 5

In the given figure, the electric lines of force emanate from A and C. Therefore, charges A and C must be positive.

Test: Electric Field Lines (NCERT) - Question 6

Figure shows the electric field lines around three point charges A, B and C. which charge has the largest magnitude?
 

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 6

From the given figure it is clear that, maximum number of electric lines of force are associated with charge C, so it must have the largest magnitude.

Test: Electric Field Lines (NCERT) - Question 7

Figure shows the electric field lines around three point charges A, B and C. which or regions of the figure could the electric field be zero?
 

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 7

From the figure, it is clear that, there cannot be a neutral point between a positive and a negative charge. Neutral point can be only there between two like charges i.e„ A and C. As magnitude of charge A is smaller than the magnitude of charge C, therefore, neutral point would lie closer to the charge A.

Test: Electric Field Lines (NCERT) - Question 8

A non-uniform electric field is represented by the diagram. At which of the following points the electric field is greatest in magnitude?

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 8

Electric field strength is maximum where the electric field lines are closer.

Test: Electric Field Lines (NCERT) - Question 9

Which of the following curves shown below cannot possibly represent electrostatic field lines?

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 9

Perpendicular to the Surface of Conductors: Electrostatic field lines are always perpendicular (at 90 degrees) to the surface of a conductor. This is because conductors contain free charges that can move freely within the material. When an electric field is applied, these free charges redistribute themselves on the surface of the conductor until the electric field inside the conductor is zero. This redistribution causes the electric field at the surface to be perpendicular to the surface.

Test: Electric Field Lines (NCERT) - Question 10

Which of the following statements is not true about electric field lines?

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 10

In a charge-free region, electric field lines can be taken to be continuous curves without any breaks.
