In the question above, charge $q_2$ is $2\mathrm{.}2{10}^{-9}C$ and charge $q_1$ has mass $0\mathrm{.}1g.$ The separation $r$ is $2\mathrm{.}9cm,$ and the angle $$ is $10\mathrm{.}2$ degrees. Find $q_1($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 $3\mathrm{.}1{10}^{-24}$ you must type ${3\mathrm{.}1}^{**}{10}^{{?}^{{?}^{?}}}-24$ in the answer box exactly in this format with no spaces. For this question you also MUST use one place after the decimal, as in the formatting example above.
