an equilateral triangle is sitting on its base and has three charged particles attached to its corners. each side of this equilateral triangle has a length of 1.3 cm. a proton is attached to its top corner. two electrons are attached to the bottom corners, one electron per corner. a) find the electric potential at the center of the triangle. (b) find the magnitude of the electric field at the center. (c) find the direction of the electric field vector with respect to the x-axis. the triangle begins to rotate clockwise with the particles having a speed of 3.2 m/s, hovering over your exam paper. (d) find the magnetic field at the center of the triangle. (e) is this magnetic field pointing toward your face or away from your face as you look down at the triangle rotating over your exam paper?
