1 point In the diagram below, if q 2 is positive then what sign is the charge on q 1 in order to produce the force required to cause the deflection in the string that supports q 1? F21 Fg = m19 Not enough information to decide. Positive Neutral O Negative 3 points In the question above, charge q2 is 1.38x10 9C and charge q1 has mass 0.18g. The separation r is 3.86cm, and the angle 0 is 16.38 degrees. Find q1 (magnitude and sign, you don't need to enter a + for positive answers but you will need to enter a - if negative). Note: the answer for this question is very small so you must use Scientific Notation. Note about format when using scientific notation. This system is very particular about entering numbers in scientific notation example to enter 3.11x10-24 you must type 3.11*10^-24 in the answer box exactly in this format with no spaces. For this question you also MUST use two places after the decimal, as in the formatting example above. Type your
