Please solve the following multiple choice and include explanation:

Problem 4. You perform two experiments (El and E2) in which you distribute charge +3Q differently on an equilateral triangle made with thin in- sulating rods. El: You put identical charges, +Q each, in three localized blobs on the ver- tices of the triangle. E2: You distribute charge +3Q uniformly on the triangle. The dashed triangle in Fig. 3 shows an imaginary equilateral triangle concentric with the insu- lating triangle. Which one of the following statements is true about the electric eld magnitude at points on the dashed imaginary triangle due to the +3Q charge? Fig. 3. Charge distribution for Problem 4. (a) It is the same everywhere on the dashed triangle only in experiment El. (b) It is the same everywhere on the dashed triangle only in experiment E2. (C) In each experiment, it is the same every where on the dashed triangle, but the magnitudes differ in the two experiments. ((1) In each experiment, it is the same every- where on the dashed triangle, and the magnitudes are equal in the two experi- ments. (6) Both in experiment E1 and in experiment E2 it varies from point to point on the dashed triangle
