Question

A nonconducting wire is bent as shown in the figure. Wire is given uniform charge density '$\lambda$'. Then electric field at origin 'O':

• A. has magnitude zero
• B. has magnitude $\frac{(2-\sqrt{2})\lambda}{4\pi\epsilon_0 R}$
• C. is along the direction $-\frac{\hat{i}+\hat{j}}{\sqrt{2}}$
• D. is along the direction $\frac{\hat{i}+\hat{j}}{\sqrt{2}}$

Answer 1

Answer: (D)

is along the direction $\frac{\hat{i}+\hat{j}}{\sqrt{2}}$

Answer 2

I am unable to determine the correct explanation for this question.
