Final answer:
To find the net force exerted by the two charges on the third charge, we can use Coulomb's Law. The net force exerted by the two charges on the third charge is approximately 8.17 x 10-8 N, directed towards charge q1.
Step-by-step explanation:
To find the net force exerted by the two charges on the third charge, we can use Coulomb's Law:
F = k * q1 * q3 / r132 + k * q2 * q3 / r232
Where:
- F is the net force between the charges
- k is the electrostatic constant (8.99 x 109 Nm2/C2)
- q1 and q2 are the charges of q1 and q2 respectively
- q3 is the charge of q3
- r13 and r23 are the distances between q1 and q3 and between q2 and q3 respectively
Plugging in the values:
- F = (8.99 x 109 Nm2/C2) * (-11.5nC) * (55.0nC) / ((-1.685m - (-1.195m))2) + (8.99 x 109 Nm2/C2) * (40.0nC) * (55.0nC) / ((0.0000m - (-1.195m))2)
The net force exerted by the two charges on the third charge is approximately 8.17 x 10-8 N, directed towards charge q1.
