How do you find the net force on a charge of an equilateral triangle?

To find net force, you have to place a charge at the centroid of triangle. Let us assume +q charge is there at centroid. Force due to each charge q,F = 3kq^2/l^2. Now, this force and force due -q charge are in same direction.

What is the force on charge q placed at the centroid of equilateral triangle?

so Net force on charge ” Q ” placed at centroid is zero.

What is vertices of equilateral triangle?

Equilateral triangle/Number of vertices

What is the vertex of a triangle?

The vertex (plural: vertices) is a corner of the triangle. Every triangle has three vertices. The three altitudes intersect at a single point, called the orthocenter of the triangle. See Orthocenter of a Triangle. In the figure above, you can see one possible base and its corresponding altitude displayed.

How do you find the resultant force of a triangle?

If we consider the positive direction of the forces to be towards the surface of the then, the formula of the resultant force is:

1. R = Fweight – Fair drag = 735 – 135 = 600 N.
2. R = F1 – F2 = 10 – 5 = 5 N.
3. R = F1 + F2 = 10 + 5 = 15 N.
4. γ = 180° – α – β (1)
5. Fx = R · cos(α) Fy = R · cos(β) Fz = R · cos(γ)

What is the force at charge Q in an equilateral triangle?

Three charges q,q,-q are placed at the vertices of an equilateral triangle, what is the force at charge q? There are two charges of magnitude q. Each of them is acted upon by two electrostatic forces of magnitude F (=q^2/4π€a^2, where a is the side of the equilateral∆) acting at an angle of 120°.

How do you find the magnitude of Q in an equilateral triangle?

If we see the forces at corner of the given equilateral triangle, The charge placed at center o should be negative. Then only the resultant force FR due to F1 and F2 will be balanced by F3 which is in the opposite direction of FR. if we equate the magnitude of FR and FQ, we will get the magnitude of Q in terms of q.

How many charges are at the corners of an equilateral triangle?

Originally Answered: Three charges +q +q -q are at the corners of equilateral triangle.The ratio of the force on a positive charge to the force on the negative charge? Now on analyzing the forces of the charge we see that the horizontal components cancel each other leaving us with the downward vertical force only.

How do you find the net force of a triangle?

To find net force, you have to place a charge at the centroid of triangle. Let us assume +q charge is there at centroid. Also, let side of triangle be l. Then, distance of each charge to centroid = l/sqrt (3) Force due to each charge q,F = 3kq^2/l^2. Now, forces due to +q charge are at angle of 60 to each other.
