Three point charges are held at the corners of an equilateral triangle,if q=2 micro columb and length =3cm what is the resultant force on the +q charge
And where is the +q charge located?

To find the resultant force on the +q charge, we need to calculate the forces exerted by the other charges on it using Coulomb's law and then find the vector sum of these forces.
Coulomb's law states that the electrical force between two charges is given by the equation:
F = k * (q1 * q2) / r^2
Where F is the force, k is the electrostatic constant (9 x 10^9 Nm^2/C^2), q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.
In this case, we have an equilateral triangle with three charges held at the corners. Let's label the charges A, B, and C. The +q charge is located at the center of the triangle.
Since the triangle is equilateral, each side length is equal to 3 cm. Hence, the distance between the charges is also 3 cm.
To calculate the forces between the charges, we need to consider the fact that the charges at the corners of the triangle will have equal magnitudes but opposite signs. From the given information, q = 2 microcoulombs.
Let's denote the charge at point A as -q, and the charges at B and C as +q.
Now, we can calculate the forces using Coulomb's law for each pair of charges:
Force between +q at B and -q at A:
F1 = (9 x 10^9 Nm^2/C^2) * ((2 x 10^-6 C) * (2 x 10^-6 C)) / (0.03 m)^2
Force between +q at B and +q at C:
F2 = (9 x 10^9 Nm^2/C^2) * ((2 x 10^-6 C) * (2 x 10^-6 C)) / (0.03 m)^2
Force between -q at A and +q at C:
F3 = (9 x 10^9 Nm^2/C^2) * ((2 x 10^-6 C) * (2 x 10^-6 C)) / (0.03 m)^2
Finally, to find the resultant force on the +q charge, we need to calculate the vector sum of these forces:
Resultant force = F1 + F2 + F3
Once you substitute the given values into the equations, you can calculate the individual forces and the resultant force on the +q charge.
