Question

The diagram shows the electric field around two charged objects.

What are the correct labels for the image?

A) W: Positive
X: Positive
B) W: Negative
X: Negative
C) W: Negative
X: Positive
D) W: Positive
X: Negative

Answer 1

Here we have been given two charged body W and X.

We are asked to determine the nature of charge.

Before coming into conclusion, first we have to understand the electric field lines.

The electric field lines are pictorial representation of imaginary lines which are drawn to denote the electric field in a graphical way.

The electric field line starts from a positive charge and ends at a negative charge.It means for positive charges the electric field lines are outward and for negative charges the filed lines will be inward.

In the given diagram,the filed lines for W is towards W itself.The same is also in case of X.

Hence both the charges must be negative in nature.

Hence the correct answer to the question will be B i.e W negative and X: NEGATIVE.

Answer 2

The correct answer is the option B which is both points X and W are negative.

Step-by-step explanation:

• In the above picture it is shown that There are two points W and X. The field of lines are entering to the both points.
• There is no line which went to X from W or from X to W.
• This Shows that both points have the same charge either positive or negative. Because both have repulsive force to each other.
• Now it is known that electric field of lines always went from positive ion and enters to negative ions.
• It means both points re negative as lines are entering both points.
