${\text{5 ms}}^{- 2}$

#### Explanation:

Force is defined as

$F = m \cdot a$

This means that the acceleration of the book will be

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

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

${\text{1 N" = "1 kg" * "1 ms}}^{- 2}$

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)#
