Question

Need answer and explanations on questions 3, 4, & 5 specifically.

A point charge q₁ = -3.7 μC is located at the origin of a co-ordinate system. Another point charge q₂ = 6.1 μC is located along the x-axis at a distance x₂ = 8.4 cm from q₁.

1)

$h1_oneDa$

What is F_12,x, the value of the x-component of the force that q₁ exerts on q₂?

N

2)

$h1_oneD2b$

Charge q₂ is now displaced a distance y₂ = 2.1 cm in the positive y-direction. What is the new value for the x-component of the force that q₁ exerts on q₂?

N

3)

A third point charge q₃ is now positioned halfway between q₁ and q₂. The net force on q₂ now has a magnitude of F_2,net= 9.032 N and points away from q₁ and q₃. What is the value (sign and magnitude) of the charge q₃?

μC

4)

How would you change q₁ (keeping q₂ and q₃ fixed) in order to make the net force on q₂ equal to zero?

Increase its magnitude and change its sign

Decrease its magnitude and change its sign

Increase its magnitude and keep its sign the same

Decrease its magnitude and keep its sign the same

There is no change you can make to q₁ that will result in the fet force on q₂ being equal to zero.

5)

How would you change q₃ (keeping q₁ and q₂ fixed) in order to make the net force on q₂ equal to zero?

Increase its magnitude and change its sign

Decrease its magnitude and change its sign

Increase its magnitude and keep its sign the same

Decrease its magnitude and keep its sign the same

There is no change you can make to q₃ that will result in the fet force on q₂ being equal to zero.
