anything Chapter 22, Problem 011 FULL scREEN PRINNER VERSTON Two partides are fixed to an x axis: partide 1 of charge q 2.52 x 10 catx 15.0 am and partide 2 of charge qz -s.760h at x 70.0 om AL what coordinate on the Kaais is the electric field produced by the partides equal to zero?

Explanation / Answer

given,

q1 = 2.52 * 10^-8 C

q2 = -5.76 * (2.52 * 10^-8) C

let at distance x from q1 the electric field is 0

electric field = k * q / distance^2

net electric field = 9 * 10^9 * 2.52 * 10^-8 / x^2 + 9 * 10^9 * -5.76 * 2.52 * 10^-8 / ((0.7 - 0.15) + x)^2

net electric field = 0

0 = 9 * 10^9 * 2.52 * 10^-8 / x^2 + 9 * 10^9 * -5.76 * 2.52 * 10^-8 / ((0.7 - 0.15) + x)^2

x = 0.393 m

coordinate in x axis = 0.15 - 0.393

coordinate in x axis = -0.243 m

coordinate on x axis where net electric field is 0 = -0.243 m or 24.3 m
