That depends what you consider "relevant to the degree". To be a "physicist" entails getting a PhD and then working in academia. However the degree is suitable background to go into a wide range of areas, including potentially: software engineering/development, banking and financial services, becoming a patent attorney, a wide range of roles in the engineering sector, and any general position anyone with a degree could apply to (such as the civil service, or a training contract at a law firm).
There are no degrees other than medicine that lead to a guaranteed job at the end, and you actually need to get through the medical degree to get that job. If you don't want to do it, and aren't motivated to do that course, then whether you even get that far is debatable. Beyond that, it is extremely bad for your would-be patients if you just went into the job with no interest in helping them and just did so to please your parents and/or society. Those people who might become your patients deserve better than that, so you should allow them that by pursuing something that interest you and benefit everyone.
