When a charged particle enters a uniform magnetic field its kinetic energy

A charged particle moving at right angles to a uniform magnetic field and starts moving along a circular arc of radius of curvature 'r' . In the field it now penetrates a layer of lead and loses 3//4 of its initial kinetic energy. The radius of curvature of its path now will be
