Question

Two uniformly long charged wires with linear densities l and 3l are placed along X and Y axis respectively. Determined the slope of electric field at any point on the line y = $\sqrt{3}$x.(slope of electric field is tan a where a is the angle that electric field make with the x axis)

• A. 3$\sqrt{3}$
• B. $\frac{\sqrt{3}}{3\sqrt{2}}$
• C. $\frac{1}{3\sqrt{3}}$
• D. $\sqrt{3}$

Answer 1

Answer: (C)

$\frac{1}{3\sqrt{3}}$

Answer 2

= +

Slope = $\frac { E _ { y } } { E _ { x } }$ = $\frac { 1 } { \sqrt { 3 } }$ ÷ 3 = $\frac { 1 } { 3 \sqrt { 3 } }$
