this is the answer : The motion blur effect created through the V-RayPhysicalCamera will strongly depends on the Shutter speed (because you need more light to get in the camera to create the effect) and the measurement of the scene. This is because it works as a real camera with real parameters.
In your scene because the movements are not really fast you will need to lower the Shutter speed (try to set it to 1 in example). This way you will get really bright result. To compensate that you can use F-number, ISO or both. (Try to set F-number to 30 and ISO to 10 in example).
Also you can use the default MB form the V-Ray settings as well which is more easy to use:
