Electrostatics Question 9
Question 9 - 2024 (29 Jan Shift 1)
Two charges of $5 Q$ and $-2 Q$ are situated at the points $(3 a, 0)$ and $(-5 a, 0)$ respectively. The electric flux through a sphere of radius ’ $4 a$ ’ having center at origin is :
(1) $\frac{2 Q}{\varepsilon _0}$
(2) $\frac{5 Q}{\varepsilon _0}$
(3) $\frac{7 Q}{\varepsilon _0}$
(4) $\frac{3 Q}{\varepsilon _0}$
Show Answer
Answer: (2)
$5 Q$ charge is inside the spherical region flux through sphere $=\frac{5 Q}{\varepsilon _0}$
