Three point charges, +6.7e-6, +2.5e-6, and -3e-6, lie along the x-axis at 0 cm, 2.4 cm, and 5.7, repectively.

What is the force exerted on q1 by the other two charges? (to the right is positive) . The coulomb constant is 8.99*10^9 N*m^2/C^2

What is the force exerted on q2 by the other two charges?

What is the force exerted on q3 by the other two charges?

x1=0.024 m, x2 =0.057 m

F12= k•q1•q2/x1² (to the left),

F13 = k•q1•q3/x2² (to the right),

F1 = F12 – F13 ( if F1>0 to the left, if F1<0 to the right)

F21= k•q1•q2/x1² (to the right),

F23 = k•q2•q3/(x2-x1)² (to the right),

F2 = F21 + F23 (to the right)

F31= k•q1•q3/x2² (to the left),

F32 = k•q2•q3/(x2-x1)² (to the left),

F2 = F31 + F32 (to the left)
