The magnitude of the electric field between two parallel charged plates is 800.0 . an electron moves to the negative plate 2.5 cm away. find the electric potential difference and the work. recall that the charge of an electron is 1.602 × 10–19 c. δv = w = × 10–18 j

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
