Question
Please show work
1. Three charges: q1 = 6 ?C, q2 = -5 ?C and q3 = 4 ?C are arranged as shown in Figure 1 below.
a. What is the magnitude and direction of the electrostatic force on q1 due to q2?
b. What is the magnitude and direction of the electrostatic force on q1 due to q3?
c. Find the magnitude and direction of the resultant electrostatic force on q1 at the origin.
Explanation / Answer
a) F12 = k*q1*q2/r^2 = -9*10^9*6*5*10^-12/0.5^2 = 1.08 N (+x direction)
b) F13 = k*q1*q3/r^2 = -9*10^9*6*4*10^-12/0.2^2 = 5.4 N (+y direction)
c) Fnet = sqrt(F12^2+F13^2) = 5.507 N
