Resultant force and F = ma

Physics · Secondary 4 · Medium · Resultant force and F = ma

A boat engine pushes the water backwards with a force of 2500 N. The total resistive force of the water on the boat is 1900 N in the opposite direction.

What is the magnitude of the resultant force acting on the boat?

$400\,\text{N}$
$600\,\text{N}$
$1900\,\text{N}$
$2500\,\text{N}$
