Four blocks of the same mass m connected by cords are pulled by a force F on a smooth horizontal surface as shown in Determine the tensions `T_(1) T_(2)` and `T_(3)` in the cords.

Explanation

To solve the problem of finding the tensions \( T_1, T_2, \) and \( T_3 \) in the cords connecting four blocks of mass \( m \) being pulled by a force \( F \) on a smooth horizontal surface, we can follow these steps:

### Step 1: Understand the System
We have four blocks of mass \( m \) connected by cords. When a force \( F \) is applied to the first block, all blocks will accelerate together with the same acceleration \( A \).

### Step 2: Calculate the Total Mass
The total mass of the system is:
\[
