Answer:

[tex]a=5\ m/s^2[/tex]

Explanation:

Two forces are 10 N and 30 N. Let us assume that two forces are acting in opposite directions. Net force will be :

F = 30 N - 10 N = 20 N

Now,

F = ma

⇒ a = F/m

So,

[tex]a=\dfrac{20}{4}\\\\a=5\ m/s^2[/tex]

So, the acceleration of the object is [tex]5\ m/s^2[/tex].
