Hi. Please help. I would appreciate if you can help me with this.

#1. (6 points) Two point charges, the first with a charge of +3.13 [AC] and the second with a charge of -4.47[AC], are separated by 25.5 [cm]. (a) Find the magnitude of the electrostatic force experienced by the positive charge. (b) Is the magnitude of the force experienced by the negative charge greater than, less than, or the same as that experienced by the positive charge? Draw a sketch with all appropriate vectors. #2. (8 points) A point charge q = +4.7[MC] is placed at each corner of an equilateral triangle with sides 210 [mm] in length. (a) What is the magnitude of the electric field at the midpoint of any of the three sides of the triangle? (b) Is the magnitude of the electric field at the center of the triangle greater than, less than, or the same as the magnitude at the midpoint of a side? Draw a sketch with all appropriate vectors. #3. (6 points) In order to work well, a square antenna must intercept a flux of at least 0.045 [Nm2 when it is perpendicular to a uniform electric field of magnitude 5.0 . What is the minimum side length of the antenna
