Question

Two blocks of equal mass m are tied to each other through a light string. One of the blocks is pulled along the line joining them with a constant force F. Find the tension in the string joining the blocks.

Answer 1

Answer:

Tension in the string is F/2

Explanation:

given:

Let a be the common acceleration of the blocks.

For block 1,

F-T=ma    …(1)

For block 2,

T = ma    …(2)

Subtracting equation (2) from (1), we get:

F-2T=0

⇒T=F/2

Answer 2

Answer:

the ANSWER is f/2

Explanation:

block 1

f-t=ma

block 2

t=ma

f-2t=ma-ma

f=2t

t=f/2
