2. Electric Potential and Capacitance
medium
Figure shows a set of equipotential surfaces. The magnitude and direction of electric field that exists in the region is .........
A
$10 \sqrt{2} \,V / m$ at $45^{\circ}$ with $x$-axis
B
$10 \sqrt{2} \,V / m$ at $-45^{\circ}$ with $x$-axis
C
$5 \sqrt{2} \,V / m$ at $45^{\circ}$ with $x$-axis
D
$5 \sqrt{2} \,V / m$ at $-45^{\circ}$ with $x$-axis
Solution
(a)
$E=\frac{10 \sqrt{2}}{1}$
$E=10 \sqrt{2}$ at $45^{\circ}$ with $x$-axis
