To solve this problem, we need to consider the forces acting on each block separately.

For block A (2kg):
- The only force acting on block A is the tension in the string, T.
- Since block A is not accelerating, the net force on it is zero.
- Therefore, T = 0

For block B (3kg):
- The force of 10N is applied to block B.
- The tension in the string, T, is acting in the opposite direction.
- The net force on block B is the difference between the applied force and the tension: 10N - T.
- Since block B is not accelerating, the net force on it is zero.
- Therefore, 10N - T = 0
- T = 10N

Therefore, the tension in the string between the two blocks is 10N.

The force applied to the 3 kg block will cause both blocks to accelerate together. The acceleration can be calculated using Newton's second law:

$$F = ma$$

where F is the net force, m is the total mass, and a is the acceleration.

In this case, the net force is 10 N and the total mass is 5 kg, so the acceleration is:

$$a = \frac{F}{m} = \frac{10 N}{5 kg} = 2 m/s^2$$

The tension in the string is equal to the force exerted by the 2 kg block on the 3 kg block. This force can be calculated using Newton's third law:

$$F_{AB} = -F_{BA}$$

where F_{AB} is the force exerted by the 2 kg block on the 3 kg block, and F_{BA} is the force exerted by the 3 kg block on the 2 kg block.

Since the 2 kg block is accelerating to the right, the force exerted by the 2 kg block on the 3 kg block must be to the left. Therefore, F_{AB} is negative.

The tension in the string is equal to the magnitude of F_{AB}, so:

$$T = |F_{AB}| = |-F_{BA}|$$

The force exerted by the 3 kg block on the 2 kg block can be calculated using Newton's second law:

$$F_{BA} = m_Ba_B$$

where m_B is the mass of the 3 kg block, and a_B is the acceleration of the 3 kg block.

The acceleration of the 3 kg block is the same as the acceleration of the 2 kg block, so:

$$F_{BA} = m_Ba_B = 3 kg \times 2 m/s^2 = 6 N$$

Therefore, the tension in the string is:

$$T = |F_{AB}| = |-F_{BA}| = |-6 N| = \boxed{6 N}$$
