Question

cated at the origin +q is located point particle with charge at point cm. Find the location of any point or the x axis where the electric field is zero along S.5 Two particles with charges q are located at y along the y axis, and two particles with charges -q are located at r td along the x axis. Fin an ex pression for the magnitude and direction of the electric field at y 2d, x 0. (Express your result as a unitless multiple of kald', where k s 1/4 rao E2s.6 A point particle with charge -q is located at the ori- gin of a coordinate system

Explanation / Answer

A) Capacitance C = eo*A/d

100*10^-6 = (8.85*10^-12*1)/d

Seperation between the paltes is d = (8.85*10^-12*1)/(100*10^-6) = 8.85*10^-8 m = 88.5 nm

B) Electric field is E =V/d = 1/(88.5*10^-9) = 11.3*10^6 N/C
