Answer 3

\(\large \boxed {\sf {\color{blue}{E = \cfrac{Q}{4\pi \epsilon _0 r^2}}}}\)

You have been given with : E = Strength of Electric Field = 100 N/C

r = distance from the point charge = 5.0 cm
Q = magnitude of charge = ?
\(\cfrac{1}{4\pi \epsilon_0 } \) = 9 * \(10^9\) \(N m^2 / C^2\)

Precaution to take : Notice, that all the other units except "r" are in SI but r is in CGS. So, convert 5 cm to meters.
