Question

find tensions in the strings​

Answer 1

Answer:

The Tension in the string will be 35.28 N and 21.56 N

Explanation:

In this situation, we are given that the block 4 kg will go downwards and the 2 kg block will go upwards and the block on the table will slide towards the left of the table side.

Hence we can write the equations

For 4 kg block

4g-T1 = 4a

T1  = 4(g-a)---eq(1)

For  2kg block

T2-2g = 2a

T2 = 2(a+g)---eq(2)

For 4kg on the table

T1-T2-f = 4a

T1-T2-μ4g = 4a

2a +2g -(4g-4a ) -0.25*4*9.8 = 4a

a = 0.98 m/$s^{-2}$

Putting this value in eq 1 and 2 we get

T1 = 35.28 N

T2 = 21.56 N

Answer 2

Answer:

The Tension in the string will be 35.28 N and 21.56 N

Explanation:

In this situation, we are given that the block 4 kg will go downwards and the 2 kg block will go upwards and the block on the table will slide towards the left of the table side.
