Electric charges of $+10\mu C, +5\mu C, -3\mu C$ and $+8 \mu C$ are placed at the corners of a square of side $\sqrt{5}$ m. the potential at the center of the square is
Text Solution
Verified by ExpertsThe correct answer is:
C
Length of each side of square is $\sqrt{2 m}$ so distance of it’s center from each corner is $\frac{\sqrt{2}}{\sqrt{2}}=1m.$
Potential at the center
$V = 9 \times 10^{9} \left[ \frac{10 \times 10^{-6}}{1} + \frac{5 \times 10^{-6}}{1} - \frac{3 \times 10^{-6}}{1} + \frac{8 \times 10^{-6}}{1} \right]$
= 1.8 × × 10 5 V
