Question
k is the unit vector pointing toward you Acharge q = 8 pC is at the orign, and a charge q2 = 6.0 pc is on the x axis at x = 9 m a) Find the force on charge q2 F12 = Ni (b) Find the force on q (c) What would your answers for parts (a) and (b) be if q2 were -6.0 HC:? Ni 12 × Ni E Show My Work (opiona) Submit Answer Save Progress 2.12.5/12.5 points I Previous Answers e on the x axis : q1--6.0 pC is at x =-3.0 m, q2 = 7 pC is at the origin, and q Ni 3--6c is at x = 3.0 m. Find the force on qi 6.0 HCc is at x -3.0 m, q2 7 ICi Three point charges are on the x axis: q1 3.3e-2 ENG Ask me anythingExplanation / Answer
a)
q1 and q2 will repel each other since both are positive charge
F12 will be along positive x axis
|F12| = K*q1*q2/r12^2
= (8.99*10^9)*(8*10^-6)*(6*10^-6) / (9)^2
=5.33*10^-3 N
Answer: 5.33*10^-3 Ni
b)
F21 will be along negative x axis
|F21| = K*q1*q2/r12^2
= (8.99*10^9)*(8*10^-6)*(6*10^-6) / (9)^2
=5.33*10^-3 N
Answer: -5.33*10^-3 Ni
c)
In this case charge will attract each other
F12 will be along negative x axis
F21 will be along positive x axis
Answer:
F12 = -5.33*10^-3 Ni
F21 = 5.33*10^-3 Ni
