Question 37: Electrostats & Capacitance

Question

Six point charges are kept $60^\circ$ apart from each other on the circumference of a circle of radius $R$ as shown in figure. The net electric field at the center of the circle is $_____$.

$(\varepsilon_0 	ext{ is permittivity of free space})$

Accepted Answer

NA

Answer

A. $-\left(\dfrac{5Q}{8\pi\varepsilon_0 R^2}\right)(\hat{i} - 3\hat{j})$

Answer

B. $\dfrac{Q}{4\pi\varepsilon_0 R^2}(\sqrt{3}\hat{i} - \hat{j})$

Answer

C. $-\dfrac{Q}{4\pi\varepsilon_0 R^2}(\sqrt{3}\hat{i} - \hat{j})$

Answer

D. $-\dfrac{5Q}{8\pi\varepsilon_0 R^2}(\hat{i} + \sqrt{3}\hat{j})$
