Explanation:

  • According to the symmetry of the equilateral triangle, the electric field at the center of the triangle is zero.

  • The electric field at the mid-point of any of the sides of the triangle is also zero due to the symmetry of the triangle.

  • The electric field at the centroid of the triangle is also zero due to the symmetry of the triangle.

  • The electric field at any other point within the triangle is not zero since it is not symmetric.

  • Therefore, there are four points within the triangle where the electric field is zero.
