Large electroscope is made with "leaves" that are 78-cm-long wires with tiny 43 g spheres at the ends. When charged, nearly all the charge resides on the spheres. If the wires each make a 26∘ angle with the vertical , what total charge Q must have been applied to the electroscope?

the answer is 4.9 × 10⁻⁶C

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
