Answer 2

Complete question:

The tension in the string connected between blocks is:

A. 60/3 N

B. 40/3 N

C. 50/3 N

D. 26 N

Answer:

The tension in the string connected between blocks is B. 40/3 N

Explanation:

The image given in the question is attached below.

F1 = 20 N; F2 = 10 N

m1 = 2 kg; m2 = 4 kg

Let the tension between the blocks be 'T'.

From diagram, F1 > F2

Thus, the block moves in the right direction.

2 Kg block:

T - F2 = 2a

T - 10 = 2a → (equation 1)

4 kg block:

F1 - T = 4a

20 - T = 4a → (equation 2)

On solving equation (1) and (2), we get,

10 = 6a

a = 10/6 = 5/3 m/s²

On substituting the value of a in equation (1), we get,

T - 10 = 2(5/3)

T - 10 = 10/3

T = 10/3 + 10

∴ T = 40/3
