To find the time (t), we can use the formula:

f = m * a

where:
f = force (20N)
m = mass (10kg)
a = acceleration

We know that acceleration is equal to the change in velocity over time:

a = (v - u) / t

where:
v = final velocity (2m/s)
u = initial velocity (0m/s)
t = time

Substitute the values into the formula to find acceleration:

20N = 10kg ((2m/s - 0m/s) / t)
20N = 10kg (2m/s / t)
20N = 20kgm/s / t
t = 20kgm/s / 20N
t = 1s

Therefore, the time (t) it will take for the object to reach a velocity of 2 m/s under the force of 20N is 1 second.
