Test: Electric Field Lines (NCERT) - Question 1

Electric field lines provide information about

Test: Electric Field Lines (NCERT) - Question 2

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

Detailed Solution for Test: Electric Field Lines (NCERT) - Question 2

The field lines of a single positive charge are radially outward.

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

Electrostatic field lines start or end only at 900 to the surface of the conductor. So curve (b) cannot represent electrostatic field lines.

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.
