The sum of the magnitudes of two forces acting at a point is 16 N. The resultant of these forces is perpendicular to the smaller force has a magnitude of 8 N. If the smaller force is magnitude x, then the value of x is

Lorentz Force: If a charge +q is moving in an electric field E, it experiences a force qE called Lorentz electric force.If the charge q is moving in a magnetic field vecB , it experiences a force (vecvxxvecB) called Lorentz magnetic force. If charge q is moving in a n electric field E as well as in magnetic field vecB simultaneously, the total force experience by the charge is the sum of these two forces and is called total Lorentz force. The direction of electric force is
