OK, leave the cable half attached and squeeze both brake arms together and let go to see if the springs pull both open with quick action. They don't have to open equally, as long as both pull away from the rim, and don't rub. Also if there are spring adjuster screws on both arms, it pays to loosen one rather than trying to put the burden all on one.
Even though the end is attached to one brake arm, you can still test for friction as I described earlier, or even simply sliding the housing up and down or the slack cable. It should slip very easily.
BTW- there are a number of good tutorials available on the net. Search "how to adjust V-brakes" or similar to find them. Review a few until you have a sense of the job, though I'm not sure they'll cover how to diagnose the cable friction problem.
An ounce of diagnosis is worth a pound of cure.
