If a negative test charge of magnitude 2 x 10-6  is placed at this point what is the force experienced by the charge.

Answer»

EA = \(\frac1{4\pi\varepsilon_0}\frac{q}{r^2}\)

EA = 9 x 10x \(\frac{2}{5^2}\)

EA = \(\frac{18\times10^9}{25}\) ⇒ 0.72 x 109 N/C

EB = \(\frac1{4\pi\varepsilon_0}\frac{q}{r^2}\) 

 = 9 x109 x \(\frac2{5^2}\)

EB = \(\frac{18}{25}\times10^9\)

EB = 0.72 x 109 N/C

E = EA + EB

E = 0.72 x 109 + 0.72 x 109

E = 1.44 x 109 N/C

F = qE

F = 6 x 1.44 x 109

F = 8.64 x 10N
