Answer 1

$\huge{\mathfrak{\underline{\underline{Solution:}}}}$

Any action that can change the state of the object is known as FORCE

Now, coming to this sum..

First, we should find the force

Formula is F = MA

There are 2 blocks and mass of each block is 5kg

Given acceleration is 1 m/s²

F = (Sum of masses of 2 blocks)(Acceleration)

F= (5+5)(1)

F= 10N

According to question,

F is 30N

we need 10N to move block and 30N is added here

Hence, the frictional force is the difference between this 30N and 10N

30-10= 20N

The frictional force between m1 and ground is k times of 10N

From this,

Value of k = 10k = 20N

k= 20/10

So, K is 2

$\huge{\boxed{\sf{K=2}}}$
