If the x-component of the velocity of an electron can be measured only to a precision of 5 × 10–2 m/s, what is the minimum uncertainty of the position of the electron in the x-direction? ( ) Group of answer choices 1 × 10–3 m 2 × 101 m 8.6 × 102 m 1.1 × 10–33 m 9.5 × 1032 m

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.)
