Answer:
The acceleration is 0.4 m/s²
Step-by-step explanation:
Given that,
Force = 10 N
Opposing force = 2 N
Mass of object = 20 kg
We need to calculate the acceleration
Using formula of newton's second law

Where, F = force
m = mass
a = acceleration
Put the value into the formula




Hence, The acceleration is 0.4 m/s²
