Explanation / Answer
l
q = 2.7*10^-6 C
q1 = q
q2 = -2q
q3 = -3q
q4 = -4q
d = 33 cm = 0.33 m
Force on q2 due to q1, F1 = [Kq1q2/d^2](-j)
= [2Kq^2/d^2](-j)
= - 1.204 j N
Force on q2 due to q3, F3 = [Kq2q3/d^2](i)
= [6Kq^2/d^2](i)
= 3.614 i N
Force on q2 due to q4, F4 = [Kq2q4/(?2 d)^2][cos45 i - sin45 j]
= [8Kq^2/(?2 d)^2][0.707 i - 0.707 j]
= 2.408*0.707[i - j] N
= 1.702 [ i - j] N
Net force on q2, F = F1 + F3 + F4
= -1.204 j + 3.614 i + 1.702 i - 1.702 j
= 5.316 i - 2.906 j
Magnitude : |F| = 6.058 N
Direction ? = Tan^-1[2.906/5.316]
= 28.66 degrees below the X axis.
