A particle with charge 7.76×10^(−8)C is moving in a region where there is a uniform 0.700 T magnetic field in the +x-direction. At a particular instant, the velocity of the particle has components Vx=−1.68×10^4m/s, Vy=−2.61×10^4m/s, and Vz=5.85×10^4m/s. What is the z-component of the force on the particle at this time?

The  z-component of the force is      

Explanation:

From the question we are told that

          The charge on the particle is    

           The magnitude of the magnetic field is  

            The  velocity of the particle toward the x-direction is  

           The  velocity of the particle toward the y-direction is

           The  velocity of the particle toward the z-direction is

Generally the force on this particle is mathematically represented as

So  we have    

  substituting values

So the z-component of the force is
