Question

Two point charges q2 = 3 x 10-6C and
q1 = 5 x 10-6 C are located at (3 ,5,1,) and
(1,3,2) m
find F12and F21 using vector form of coulomb 's law
Also, find their magnitude

Here, q2 = 3 X 10-6 C, q1 = 5 X
10-6 C
â€‹vector r2 = 3 i^ +5j→ +

→r12 = →r2 - →r1 = (2 i^ + 2j⏜
-k)^→r12 =22 + 22 + (-1)2 = 3 m
r12^ = →r12→r12 =2 i^ + 2j^ -k^3

→F21 = kq1q2r212 r12^ = (9 X 109) (5 X 10-6) (3 X 10-6) 32 X
