Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

KonstantinChe [14]

Let 10 nC and 20 nC charge is placed at "d" distance

now let say we will have a point at distance "x" from 10 nC at which electric field will be zero

now we will have

$E_1 = E_2$

$\frac{kq_1}{x^2} = \frac{kq_2}{(d-x)^2}$

now plug in all data

$\frac{k(10 nC)}{x^2} = \frac{k(20 nC)}{(d-x)^2}$

$\frac{10}{x^2} = \frac{20}{(d-x)^2}$

square root both sides

$\frac{1}{x} = \frac{\sqrt2}{d - x}$

$d - x = \sqrt2 x$

$d = x(1 + \sqrt2)$

$x = \frac{d}{1 + \sqrt2}$

so yes there will exist a point between 10 nC and 20 nC charge at which electric field will be zero

Set up the problem with the conversion rates as fractions where when you multiply the units cancel out leaving the desired units behind.

$( \frac{ 5 cm}{1 sec} ) *( \frac{1m }{100cm})*( \frac{1km}{1000m} )*( \frac{1mi}{1.6km} ) = 0.00003125 mi/sec \\ \\ ( \frac{0.00003125 mi}{1sec} )*( \frac{60sec}{1min} )*( \frac{60min}{1hr} )=0.1125 mi/hr$
