yes it can be fixed but how you do it depends on what brand and model brake you have. There are springs in each brake arm that pull the pad back away from the rim. These springs are adjustable. Usually there is a tiny screw on each brake arm that adjusts the spring tension. I suggest you tighten screw for the spring on the right brake arm to increase the spring tension on that side and pull the arm away from the rim. When the tension in both arms is balanced they will both be equal distance from the rim. Turn the screw a little bit at a time and squeeze the brakes a few times until things look centered.
NOW if the pad is jammed under the TIRE, that is something very different and potentially more dangerous.
