What can be inferred from the convergence of electric field lines in a diagram?.

- B.The presence of a negative charge.
- C.The electric field is uniform.
- D.The electric field strength is zero.
Model answer
What a good answer should say
- The presence of a negative charge.
Explanation
Why this works
When electric field lines converge towards a point, it indicates the presence of a negative charge at that point. This is because electric field lines originate from positive charges and terminate at negative charges.
The implication is that the behavior of charges in the vicinity of this point will be influenced by the attractive force exerted by the negative charge. Thus, this conclusion helps in understanding how charges interact within electric fields.
