Pulling Two Blocks

In the situation shown in the figure, a person is pulling with a constant, nonzero force F on string 1, which is attached to block A. Block A is also attached to block B via string 2, as shown.

For this problem, assume that neither string stretches and that friction is negligible. Both blocks have finite (nonzero) mass.

How does the magnitude of the tension in string 1, exttip{T_{ m 1}}{T_1}, compare with the tension in string 2, exttip{T_{ m 2}}{T_2}?

Block A has a larger acceleration than block B. Block B has a larger acceleration than block A. Both blocks have the same acceleration. More information is needed to determine the relationship between the accelerations.

Explanation / Answer

Part A

Which one of the following statements correctly descibes the relationship between the accelerations of blocks A and B?

the two mass block will have the same acceleration . as the force is applied to the system and due to string constraint they will have same acceleration

Both blocks have the same acceleration.

part B

How does the magnitude of the tension in string 1, T1 , compare with the tension in string 2, T2 ?

let the acceleration be a

now ,

t2 = mass of block 2 * a

t1 =mass if block A * a + t2

so we can see that t1> t2

T1>T2
