q1-----30cm-----q2-----------45cm----------q3

see Coulomb's law.

Use superposition. First find the effect 1 has on 2. Then find the effect 3 has on 2. Then addthem together paying close attention to direction.

Same for part b

To calculate the net force on q2 and q3 due to the interaction between the charges, we need to use Coulomb's Law.

Coulomb's Law states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The formula is given as:

F = (k * |q1 * q2|) / (r^2)

Where:
- F is the force between the charges q1 and q2
- k is the electrostatic constant, approximately equal to 9.0 x 10^9 Nm^2/C^2
- q1 and q2 are the magnitudes of the charges
- r is the distance between the charges

Let's calculate the net force on q2 and q3:

a. Calculate the net force on q2:
To find the net force on q2, we need to sum up the forces it experiences due to q1 and q3.

Force between q1 and q2:
F1-2 = (k * |q1 * q2|) / (r1-2^2)
F1-2 = (9.0 x 10^9 Nm^2/C^2) * (2.0 MC) * (3.0 MC) / (0.30 m)^2

Force between q2 and q3:
F2-3 = (k * |q2 * q3|) / (r2-3^2)
F2-3 = (9.0 x 10^9 Nm^2/C^2) * (3.0 MC) * (6.0 MC) / (0.45 m)^2

Finally, to find the net force on q2, we sum up F1-2 and F2-3:
Net Force on q2 = F1-2 + F2-3

b. Calculate the net force on q3:
To find the net force on q3, we need to sum up the forces it experiences due to q1 and q2.

Force between q1 and q3:
F1-3 = (k * |q1 * q3|) / (r1-3^2)
F1-3 = (9.0 x 10^9 Nm^2/C^2) * (2.0 MC) * (6.0 MC) / (0.75 m)^2

Force between q2 and q3:
F2-3 = (k * |q2 * q3|) / (r2-3^2)
F2-3 = (9.0 x 10^9 Nm^2/C^2) * (3.0 MC) * (6.0 MC) / (0.45 m)^2

Finally, to find the net force on q3, we sum up F1-3 and F2-3:
Net Force on q3 = F1-3 + F2-3

By substituting the values into the equations and performing the calculations, you can find the net forces on q2 and q3.
