Two connected masses are being pulled from the side as shown above with a force of $F = 30 N$. Take $m_1 = 2 kg$ and $m_2 = 3 kg$. Kinetic friction acts on both of the masses as they accelerate, where $\mu_k = 0.2$ for both of the masses involved.

Determine the tension $T$ in the cord connecting the two masses.

A

$7.29 N$

B

$10.9 N$

C

$12.0 N$

D

$24.1 N$

E

$30.0 N$
