Question

Which statement is the correct representation of these electric field lines?

A. Both sources are positively charged.

B. Both sources are negatively charged.

C. Source A is negatively charged and source B is positively charged.

D. Source A is positively charged and source B is negatively charged.

Answer 1

C. Source A is negatively charged and source B is positively charged.

Step-by-step explanation:

As per the properties of electric field lines we know that electric field lines originated out from the positive charge and then terminated back into the negative charge.

As per the given presentation of field lines we can see that field originated out from charge placed at B and these field lines again terminated into the charge placed at A.

So here the charge must be positive at position of B and it is negative at position of A.

so correct answer will be

C. Source A is negatively charged and source B is positively charged.

Answer 2

Note that the electric field lines begin from the higher voltage to the lower

Because the negative pole is lower voltage than the positive pole

The lines go out the positive charges and go in the negative charges

Then, the correct statement is:

C. Source A is negatively charged and source B is positively charged.
