Consider an equilateral triangle with sides measuring 1.0 m in length. at each point of the triangle is a +2.0 μc charge. calculate the coulomb force on each charge. recall that forces are vectors and thus your answer will require a magnitude and direction for each of the three forces.

Th magnitude of each Force will be

Explanation:

Given:

Since all the charges are identical and distance between them is same so magnitude of the force between each charge is equal.

Let F be the force between the particles. According to Coulombs Law we have

Now the the force on any charge by other two charges will be F and the angle between the two force is

Let be the force on nay charge by other two

By using vector Law of addition we have

The angle made by the resultant vector will be

the higher the current the higher the mag field around it the higher the influence on the compass

that would be because of both gravity and friction. so     c
