Please be more specific. At the very least, post the complete formula. I assume that the dots mean that there's more than V and m on the right-hand side. What do those symbols represent? Electric field strength, voltage and mass? Total energy, potential energy and mass? Where did you find the formula? If it's a book, tell us the name and the page number. If possible, link directly to that page at google books.
