Question

Three charges exist under the following conditions: q1 = 2.3x10-6C, q2 = -1.7x10-6C, q3 = -3.4x10-6C, r12 = 0.13 m, and r23 = 0.35 m.

a) What direction is the electric field that q3 'feels' due to q1?

b) What si the direction of the electric field that q3 'feels' due to q2?

c) What is the magnitude of the electric field that q3 'feels' due to q1?

d) What is the magnitude of the electric field that q3 'feels' due to q2?

e) What is the magnitude and direction of the total electric field that q3 'feels'?

a) towards q1

b) towards q3

c) E31 = (9*10^9*2.3*10^-6)/(0.48^2) = 89843.75 N/C

d) E32 = kq2/r23^2 = (9*10^9*1.7*10^-6)/(0.35^2) = 124897.95 N/C

e) Enet = 124897.95 - 89843.75 = 35054.2 N/C towards q3
