Determine whether each statement concerning electrical circuits is true or false. The electrons in a circuit move from the negative to the positive battery terminal. In a light bulb circuit, when the battery voltage is increased the bulb brightness decreases. A standard alkaline battery (AAA, AA, C, D) has a voltage of 3 V.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
