What is the magnitude of the electric force of attraction between uranium nucleus and its innermost electron if the distance between them is 8.9x10 pm (picometers)? Express your final answer in scientific notation. 3. A hypothetical plane of equilateral hexagon has six charged particles on each of its vertices. If Q1 has a charge of 7nC (nanoCoulomb) and there is an increasing amount of charge per each vertex by a factor of seven up to Q6, what would be the net force experienced by Q1? Assume that the charge sign alternates from positive to negative, starting on Q1. *these 3 questions have no correlations to one another.

2. Given that q = +10 µC and d = 15 cm in the figure to the right: a. What is the net electrostatic force exerted 91 = +9 93 = +3.0g 2 = -2.0g on q2? b. How does your answer change if d is tripled? 3. Use the figure from question 2. Suppose that q2 is allowed to move left or right along the line connecting all of the charges. If q = +10 µC find the distance from q1 where q2 will experience a net electrostatic force of 0 N. The distance between q1 and q3 is fixed at 35 cm. (Hint: Let x be the distance between q. and q2, and the distance between q2 and q3 is [35 cm-x].) (quadratic warning)
