Thanks.cnh1995 said:You should first find the distance of the orthocenter from the vertices. Since this is an equilateral triangle, orthocenter is the centroid. You can use trigonometry or pythagoras theorem to find the distance. After that, calculate field intensity due to each charge. The direction of the field will be along the line joing the charge and the orthocenter, either away from or towards the charge. Then you can add the fields "vectorially" to get the resultant field.
The electric intensity at the orthocenter of a triangle is the measure of the strength and direction of the electric field at that point. It is determined by the charges and distances of the vertices of the triangle.
The electric intensity at the orthocenter of a triangle is calculated by taking the sum of the electric intensities at each vertex of the triangle, multiplied by the cosine of the angle between the line connecting the vertex to the orthocenter and the direction of the electric field.
Yes, the shape of the triangle does affect the electric intensity at the orthocenter. The electric intensity is determined by the distances and angles between the vertices, so a change in the shape of the triangle will result in a change in the electric intensity at the orthocenter.
The electric intensity at the orthocenter of a triangle is the vector sum of the electric intensities at each vertex, while at other points on the triangle, the electric intensity is only determined by the electric field from nearby charges.
Yes, the electric intensity at the orthocenter of a triangle can be negative. This indicates that the direction of the electric field at that point is opposite to the direction of the electric field at the other vertices of the triangle.
