MHT CET 2026 20th April Morning Shift | Electrostatics Question 5 | Physics

Four electric charges $+q$ , $+q$ , $-q$ , and $-q$ are placed in order at the corners of a square of side '$2r$'. The electric potential at a point midway between the two negative charges is

$\dfrac{1}{4\pi\epsilon_0}\,\dfrac{2q}{r}\left[\dfrac{1}{\sqrt{5}} - 1\right]$

$\dfrac{1}{4\pi\epsilon_0}\,\dfrac{q}{r}\left[\dfrac{1}{\sqrt{5}} + 1\right]$

$\dfrac{1}{4\pi\epsilon_0}\,\dfrac{2q}{r}\left[1 - \sqrt{5}\right]$

$\dfrac{1}{4\pi\epsilon_0}\,\dfrac{q}{r}\left[1 + \sqrt{5}\right]$

An electric dipole of length 2 cm is placed with its axis making an angle of $60^{\circ}$ to a uniform electric field of $10^{+5} \mathrm{~N} / \mathrm{C}$. If it experiences a torque of $9 \sqrt{3} \mathrm{Nm}$, the magnitude of the charge on the dipole is $\left(\sin 60^{\circ}=\frac{\sqrt{3}}{2}\right)$

$7 \times 10^{-3} \mathrm{C}$

$8 \times 10^{-3} \mathrm{C}$

$9 \times 10^{-3} \mathrm{C}$

$\frac{9}{2} \times 10^{-3} \mathrm{C}$
