${5 ms}^{- 2}$ $"5 ms"^(-2)$

Force is defined as

$F = m \cdot a$ $F = m * a$

This means that the acceleration of the book will be

$a = \frac{F}{m}$ $a = F/m$

You need to convert the mass of the book from grams to kilograms because

$1 N = 1 kg \cdot {1 ms}^{- 2}$ $"1 N" = "1 kg" * "1 ms"^(-2)$

Put all this together to get

$a = F/m = (1 color(red)(cancel(color(black)("kg"))) * "ms"^(-2))/(200 * 10^(-3)color(red)(cancel(color(black)("kg")))) = 5 "ms"^(-2)$
